I used the refugee term in the sense of "they came here to escape poverty and gang wars", not "the State Dept allowed them in".

And "Why not"? Because of my point: Syrian war is having a very real, direct impact on the other countries, and is violating the Non-Aggression Principle. So even if someone is a Libertarian or non-absolute Pacifist, it could be argued those countries most affected by refugees have the right to self-defense against Syrian combatants.
