It is the 'War on drugs.' Yes it is a war.
When one person enters the US and commits just one murder, rape or assault they should have been stopped by whatever means prior to the act, beginning with proper vetting. Yet they come in illegally so no vetting process. When drug cartels send weapons of mass destruction into the country, which they are doing, killing around 100,000 annually, they should be stopped by whatever means necessary. It is a mandate of US government to protect it's citizens.
Drug cartels are not seeking asylum. They do not consider your life or welfare.
If you wish to make this a Christian issue consider these words;
Romans
' Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. 2 Consequently, whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. 3 For rulers hold no terror for those who do right, but for those who do wrong. Do you want to be free from fear of the one in authority? Then do what is right and you will be commended.
Peter
Submit yourselves for the Lord’s sake to every human authority: whether to the emperor, as the supreme authority, 14 or to governors, who are sent by him to punish those who do wrong and to commend those who do right. 15 For it is God’s will that by doing good you should silence the ignorant talk of foolish people.
The evil men who choose to commit these crimes remind me of these words.
'With the reasonable man I will reason.
With the fool I will plead,
But to the tyrant I will show no quarter.'
