I do find it ironic that the US is criticized so heavily by Europe for being the policeman of the world sometimes. Now, those same people are calling for their government to bend over where they have no real obligation to.
My position in all of this is that something has to be done to help people fleeing from war, but taking in so many economic migrants is not wise. It has long running consequences that I don't think people consider. Doing what feels right at the time may end up being worse for your country.
