well, we fight that deal every day with N Korea and China and Russia

[what's up]

Many of these people are western trained; many are citizens in the west. China and Russia don't want to destroy us completely because they have trade deals with us. ISIS has no qualm at all. (N. Korea doesn't have the IT experts and they're pretty much clueless about social media).

When you have a die hard ISIS member trained in Boston, familiar with social media and American culture who is now at a high level of leadership in ISIS you have a problem which border control won't eliminate.
