We can’t run our own country responsibly yet can’t seem to resist getting involved in the affairs of other countries. It inevitably it has blowback from others that had relationships with those countries. Obama said that Assad in Syria had to go and that then created the power vacum that created a civil war. Why did we invade Libya as Ghadaffi had done what we asked?
There are outside forces that thrive on turmoil and divide. You can bet that these forces that push multi-culturalism upon us will inevitably turn it against the USA.
Those who push multiculturalism protest against defense.
