Well, US gov (Clinton and Obama) created this refugees in the first place. They are all coming from the areas that this administrations ruined in one way or another.
That's a good reason, why US government and taxpayers, not individual corporate entities, should take responsibility and handle this systematically instead of banning the entry.
(btw, somehow you forgot Bush with Iraq and Afghanistan)
You might want to scroll back your timeline a bit. It was Bush's invasion of Iraq in 2003 that created these refugees. Expensive bit of election-securing that.
It is sade that comments like yours get downvoted. It seems noone here in HN wants to listen to the truth. Perhaps they are ignorant or conscientiously aware of what the States has done to Syria and want to muffle the truth. Reality hurts, does it?
