We are NOW 'as in the days of Noah' and 'all is peaceful, all secure and then sudden destruction will come'. 2 Thess 5:3
1 Thessalonians 5:3 could include reference to when, near the end of the future tribulation of Revelation chapters 6 to 18 and Matthew 24, at the 2 witnesses' death at the legal end of the Antichrist's 3.5-year worldwide reign (Revelation 11:8,15, Revelation 13:5-18), the unsaved world will rejoice and make merry because it will then be free from the tormenting plagues from the 2 witnesses (Revelation 11:10,6). But little will the unsaved world realize that the plagues of the 7 vials of God's judgment and wrath will then be poured out upon it (Revelation 16). And then Jesus will return and bring the 2nd-coming judgment and wrath of God (Revelation 19:11 to 20:3).

Expect the Sixth Seal disaster as the next prophesied event!
Instead, first expect the last 3 of the 4 horsemen (Revelation 6:4-8), who represent a horrible future war which will begin the future tribulation of Revelation chapters 6 to 18 and Matthew 24, and which war will, with its aftermath of famines and epidemics, end up killing 1/4 of the world (Revelation 6:8). The "great sword" of this war (Revelation 6:4) could be Israel's nuclear weapons.
One way this war could happen is the U.S. could undertake a massive buildup of the Iraqi Army, initially to prevent the Islamic State militant group (also known as ISIS, or ISIL) from taking over Iraq, and Syria, and all the rest of the Middle East, and eventually so that the Iraqi Army can serve as a proxy army, for the U.S. and Israel, for an all-out ground invasion of Iran, in order to end Iran's nuclear weapons program and extremist regime. As part of the buildup of the Iraqi Army, the U.S. could reinstall much of the former Iraqi Baathist military hierarchy (i.e. that which existed under Baathist Saddam Hussein), to run the present Iraqi Army more efficiently and ruthlessly.
And if the current, Shiite-dominated government of Iraq balks at any return of a Baathist-dominated military (which cruelly suppressed the Iraqi Shiites under Saddam Hussein's rule), or balks at any invasion of fellow-Shiite Iran, this could lead the CIA, MI6, and the Mossad to bring about a Baathist coup d'etat in Iraq. For they could see a well-run, Baathist Iraqi Army and government as the only way to keep ISIS/ISIL under control, and the only way to eventually invade and defeat Iran, which invasion the Iraqi Baathists could agree to perform, for they see meddling, non-Arab Iran as a great enemy of Arab autonomy.
To help get the Iraqi masses and the world behind the idea of an all-out Iraqi invasion of Iran, "false flag" operations could be managed by the CIA, MI6, and the Mossad by which it will be made to seem that (non-Arab, Persian) Iran is attacking the Iraqi Sunni Arabs and their little children terroristically with "dirty bombs" made from Iranian-enriched uranium, so that the Iraqi Arab masses will become enraged and begin to call for all-out retaliation against (what they could call) "the vile Persians". And the world could see an Iraqi invasion of Iran as being completely justified by self-defense.
But then, right when Iraq is all ready to invade Iran, the ultra-Orthodox Jews in Israel (who by that time could be led by a great miracle-working false Messiah: cf. Matthew 24:24) could completely destroy the Muslim Dome of the Rock and the Al Aqsa Mosque (the 3rd-holiest sites in Islam) on the Temple Mount in Jerusalem, to clear the site for the building of a 3rd Jewish temple (Revelation 11:1-2, Matthew 24:15, Daniel 11:31,36; 2 Thessalonians 2:4). This could so enrage Muslims worldwide, including the (Muslim) Iraqi Army, that the Iraqi Baathist Generals could see it as a perfect excuse to abandon the plan to invade huge Iran, and instead (pretending that they are doing so in the name of Islam) turn and send their vast army against the little territory of Israel, completely defeating and occupying it (Daniel 11:15-17; in verse 17, the original Hebrew word translated as "daughter" is "bath").
But this wouldn't be the ultimate reason for the Baathist attack, which could continue on south to also defeat and occupy Egypt (Daniel 11:15). For Egypt is ruled by the U.S.-supported Egyptian Army, which the Baathists could see as being a puppet of the U.S., just as they could see Israel as being a colony of the U.S. Baathism's ultimate aim is to unite all Arab lands from Oman to Morocco into one massive, powerful United Arab States free of all foreign hegemony.
The all-out Iraqi attack on Israel could be joined by the entire (Baathist) Syrian Army (with all of its missiles, many still secretly tipped with nerve agents), as well as by all of Iran's long-range missiles and all of Hezbollah's and Hamas' missiles and guerrillas. Israel could find itself suddenly attacked from 3 directions at the same time, with tens of thousands of missiles raining down on its cities and military bases, and tens of thousands of Iraqi tanks (meant to defeat and occupy huge Iran) pouring across its borders. As Israel starts to see its little sliver of land completely overrun, and sees that its total defeat and occupation is imminent and assured, in retaliation it could drop nuclear bombs on Baghdad, Damascus (Isaiah 17:1), Tehran, and other major cities of Iraq, Syria, and Iran.
There could be so many nuclear explosions sending so much radioactive dust and ash so high into the atmosphere that it could be blown eastward and fall on hugely-populated South Asia, ruining so many crop fields and immune systems there with radiation that 1/4 of the world's population could end up dying from the war and its aftermath of famines and epidemics. This could fulfill the horrible war which will begin the future tribulation of Revelation chapters 6 to 18 and Matthew 24, which war will, with its aftermath of famines and epidemics, end up killing 1/4 of the world (Revelation 6:4-8). The "great sword" of this war (Revelation 6:4) could be Israel's nuclear weapons. This war could be blamed not only on the religious fundamentalism of Islam and Judaism, but also on religious fundamentalism in general, and so could lead to a worldwide crusade against all forms of religious fundamentalism, including Christian fundamentalism, i.e. the (correct) idea that the Bible is wholly true (2 Timothy 3:16, Matthew 4:4) and that all other religions are cursed (Galatians 1:8-9, John 14:6, John 3:36, Acts 4:12).
