There were several videos like this which were just karate demos, nothing more.
What? This is a real fight. I've been in real fights and I know one when I see it.
When ISIS volunteers are also trained in martial arts and in gun use by the Israeli government
and by our own CIA, these karate tricks might backfire.
First of all, there was no karate used here. They were typical combinations of straight crosses and some hooks. Second, people shouldn't live in fear of those ISIS cowards; and plenty of Americans are trained in, and conceal carry, handguns, as well as know how to fight . Remaining passive won't stop ISIS from attacking you, so your point is null.
