Civil war is what we had 1861-1865, between Americans.
Syrian jihadis, even if invited by our own government, would be a foreign invasion.
Repelling a foreign invasion is just a plain old war.
The government may well be on their side.
But .. they will not act like they’re at war. Their attacks will be random and stealth in nature .. exactly like the attacks we’ve seen in Paris and the UK.
Besides which, there are already a bunch of them here .. they have Islamic terror cells all across America.
How easy will it be for them to migrate here and then slip silently into the terror cell locations ..??
Yes, it will be “a war” .. but it will not be like anything we have ever dealt with before.
