Note that while sola scriptura will indeed save you spiritually one day, just as it does today (2 Timothy 3:15 to 4:4), it won't save you physically before the religious courts of the future Antichrist. For he will slaughter (by beheading) all Biblical Christians that he can get his hands on (Revelation 13:7-10, Revelation 14:12-13, Revelation 20:4-6).
Also, read Mark 13:9-13 as applicable to you today, if you are a Biblical Christian. For in our future, "political correctness" will make Biblical Christianity "hate speech", because the Bible says that homosexuality is a sin (Romans 1:26-27) and that Christianity is the only way to be saved (John 14:6, John 3:36, Acts 4:12), and that all other religions are cursed (Galatians 1:8-9).
Be prepared to be arrested and tried before even secular, U.S. courts of law for the violation of "hate speech" laws which will be instituted in our future (by the Supreme Court, without any approval from the People in Congress). When you go to trial, remember Mark 13:9-13, and testify as the Holy Spirit gives you at that time. But don't expect to be set free after your testimony. You must be willing to face imprisonment and even execution for the truths of Jesus Christ and His Word the Holy Bible (Matthew 24:9-13, Mark 8:34-38, John 8:31b).

Are you suggesting a physical war?
If so, note that under the Old Covenant, murder was forbidden (Deuteronomy 5:17), whereas killing in a war commanded by God was required (1 Samuel 15:3). But under the New Covenant, which Christians are under (Matthew 26:28, Jeremiah 31:31), Christians are commanded never to harm anyone, even in self-defense (Matthew 5:39, Matthew 26:52). They are to be as harmless as doves (Matthew 10:16c). For Christians are commanded to love even their enemies (Matthew 5:44), and this means that they must do them no harm (Romans 13:10a, Matthew 7:12).
It is the meek who will inherit the earth (Matthew 5:5, Psalms 37:11).
Christians don't employ physical weapons or any other violence against people (2 Corinthians 10:3-5, Ephesians 6:12-18). Instead, Jesus at his 1st coming set the example for what believers are to do when they are physically attacked by people (1 Peter 2:19-23). They are to go meekly like sheep to the slaughter (Romans 8:36), just like Jesus did (Isaiah 53:7). Obedient believers don't fear death (Hebrews 2:15), and don't love their lives unto death (Revelation 12:11b), but hate their lives in this world, so that they might retain eternal life (John 12:25, Mark 8:34-38). For obedient believers know that death is no loss for them, but gain (Philippians 1:21), as it brings their still-conscious souls into heaven to be with Jesus (2 Corinthians 5:8), which is far better than remaining in this world (Philippians 1:23).
During the future tribulation of Revelation chapters 6 to 18 and Matthew 24, believers (not in hiding) will have to face martyrdom with patience and faith to the end (Revelation 13:7-10, Revelation 14:12-13, Revelation 20:4, Matthew 24:9-13), just as believers have always had to spiritually overcome in the face of martyrdom (e.g. Revelation 2:10-11).
Note that "defend your constitutional rights" could easily be misinterpreted by some of your readers as referring, for example, to how the U.S. government is currently going after the 1st Amendment's freedom of religion by requiring Christians to support abortions and same-sex marriages. For example, a Christian pharmacy has to sell the morning-after abortion pill, and a Christian bakery has to make a cake for a homosexual wedding.
Also, the government will eventually outlaw even speaking against homosexuality or abortion, calling it "hate speech", thereby further trashing the 1st Amendment. The way that this will be done is by claiming that speech against homosexuality or abortion presents a "clear and present danger" (Schenck v. U.S.) to homosexuals and abortion clinics, as such speech could lead to violent attacks against them, such as the mass shooting at a gay club in Orlando, or when a man attacked an abortion clinic claiming to be "a warrior for the babies". Of course, from a pacifist's point of view, nothing about Romans 1:26-27, for example, contradicts Matthew 5:39. So simply saying that homosexuality is a sin in no way supports violence. But the connection could still be made precisely (i.e. as an excuse) in order to squelch Christians' Constitutional rights to free speech and freedom of religion.
Could then the war-makers among the U.S. populace (i.e. as opposed to its pacifists) call for a "NEW American Revolution", this time a violent overthrowing of the current U.S. government, especially its Supreme Court, in order to restore the Constitutional freedoms of religion and speech, not to mention privacy?
Or, the war-makers could just be more patient, and wait a little bit longer (peacefully) for Jesus to return from heaven and rule the world (Revelation 19:7 to 20:6).
For, presently, any violent rebellion against the U.S. government will simply be quashed (cf. the pathetic end to the Burns, Oregon standoff). For Obama's firing of hundreds of generals, and then the JADE HELM exercises, could all have been precisely to prepare for the day when the U.S.'s own federal military forces will be ordered to wipe out all armed militias throughout the U.S. (thereby trashing yet another amendment, the 2nd), calling the militias "an imminent threat to national security", that is, an imminent threat to an anti-Christian federal government, which will want to help prepare the way for the future Antichrist's world takeover (Revelation 13:7-18).
But before the Antichrist takes over the world and makes armed rebellion against him impossible (Revelation 13:4b,7), and even before the U.S. government has wiped out all armed militias in the U.S., could such militias unite across the country, and rise up together at the same time, declaring their all-out rebellion against the federal government, because of its (future) tyranny? And could they try to justify their rebellion in a document, which could have points laid out in a structure and wording similar to the Declaration of Independence, which they could call the:
"NEW Declaration of Independence
"When in the course of human events, it becomes necessary for the People of a great nation to dissolve the political bands which have being placed upon them by a single federal power, and to restore the freedoms which the Laws of Nature and Nature's God have entitled the People, it is reasonable to expect the People to declare the specific causes which have impelled them to violent rebellion.
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.
"That to secure these rights, Governments are instituted among men, deriving their just powers from the consent of the governed.
"That whenever any form of government becomes destructive of these ends, it is the Right of the People to alter or abolish it, and to institute a new Government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their Freedom and Happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience has shown that mankind is more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object, evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such a Government, and to provide new guards for their Freedom and Happiness.
"Such has been the patient suffering of the People of these United States, and such is now the necessity which constrains them to abolish their former system of federal government. The recent history of this government, especially in its Executive and Judicial Branches, is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over the People of these United States. To prove this, let facts be submitted to a candid world:
"The Executive has refused his assent to laws, the most wholesome and necessary for the public good. For the Executive has trampled upon even the highest laws of these United States, embodied in our Constitution. For the 4th Amendment declares the right of the People to be free from all unreasonable searches, and no warrants shall be issued, except upon probable cause. Yet the Executive now, with the help of computers and compliant corporations, continually spies upon all the People, and without any probable cause. For it tracks everywhere the People go through their cell phones, via "StingRay" devices and compliant cell phone companies, and through license-plate reading cameras set up at major intersections. And the Executive tracks every letter, magazine, catalog, or package that the People send or receive through the U.S. Mail, Federal Express, UPS, DHL, or any other courier, through the compliance of these companies. And the Executive tracks everything that the People buy with a credit or debit card, through compliant bank, credit card, and retail companies. And it tracks the People's Ad Choices and Catalog lists, and even sometimes makes insulting additions to them.
"And the Executive tracks everything that the People watch on cable TV or the internet, through compliant cable, telecom, ISP, and internet companies and forums. And it tracks everything they say on the internet. And it tracks every website and web page they view. And it tracks every phone call they make. And it tracks everything they say or hear on every phone call. And it tracks everything they do in public places by employing facial recognition and spy cameras in almost every store and restaurant, and while walking along public streets. And it listens in on everything they say in their homes, cars, or anywhere else, by remotely and secretly tapping into the microphones on their cell phones, landline phones, computers, televisions, home-security devices, online-shopping audio devices, automobile-navigation devices, etc., so that the 4th Amendment right to Privacy for the People has been completely obliterated by the Executive.
"Also, the Executive has secretly handed over the personal information (including the weekly and daily schedules) of some U.S. citizens to 'friendly' foreign intelligence agencies who see these citizens as potential threats to their national security. In this way, the Executive has exposed these citizens to surveillance and possibly even murder by foreign intelligence agencies operating (with the knowledge and consent of the Executive) on U.S. soil. The Executive allows such a setup as this so that it can, in turn, if deemed necessary, surveil, and even murder, citizens of foreign 'friendly' nations, in their own countries, if it deems these foreigners to be dangerously hostile to U.S. national security.
"Also, the Executive, and the Judiciary at its highest level, have trampled upon the 1st Amendment, which declares that the Government shall institute no law which prohibits the free exercise of religion. For they have created and enforced laws, with no assent from the People in Congress, requiring Christians to support abortions and same-sex marriages. For example, a Christian pharmacy now has to sell the morning-after abortion pill, and a Christian bakery now has to make a cake for a homosexual wedding.
"Also, the Executive, and the Judiciary at its highest level, [will] have trampled upon the 1st Amendment's declaration that the Government shall institute no law which abridges the freedom of speech. For they [will] have created and enforced laws, with no assent from the People in Congress, forbidding any speech which denigrates homosexuality or abortion, calling it "hate speech", even though the Bible itself shows that homosexual practices are sinful (Romans 1:26-27), and that unborn children have consciousness (Luke 1:41).
"Also, the Executive, and the Judiciary at its highest level, [will] have trampled upon the 2nd Amendment, which declares that the Government shall institute no law which infringes upon the right of the People to keep and bear arms. For they [will] have created and enforced laws, with no assent from the People in Congress, forbidding any civilian to own or use any firearm at any time.
"In every stage of these Oppressions, we the People have petitioned for redress. Our repeated petitions have been answered only by repeated injury. A Government, which is thus marked by every act which may define Tyranny, is unfit to rule a free people.
"We, therefore, the People of these United States of America, appealing to the Supreme Judge of the World, the Almighty God, for the rectitude of our intentions, do, in the Name, and by the Authority of the People, solemnly publish and declare the Freedom of the People, that they are absolved from all allegiance to the U.S. federal government. And for the support of this Declaration, with a firm reliance on the Protection of Divine Providence, we mutually pledge to each other our Lives, our Fortunes, and our Sacred Honor."
At some point in our future, could millions of "patriots" in armed militias across the U.S. add their John Hancocks to such a document as this, knowing that by doing so they will make themselves liable to being arrested, tortured, and murdered by the federal government?
Better to leave politics alone, and be arrested, tortured, and murdered not for being violent, or for promoting violence, but rather for being a pacifist, and for promoting the peace, love, and faith of Jesus Christ and his Biblical gospel (Matthew 24:9, Mark 8:34-38).
Maranatha, Come, Lord Jesus Christ, and rule upon this earth (Revelation 19:7 to 20:6, Revelation 22:17a,20).
1 Peter 1:24 ¶For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away:
25 But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you.
1 John 2:17 And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
