Do you believe that the State Department, CIA, FBI, and DHS is not adapting to the threat? Why is closing our doors to the world and turning a cold shoulder to innocents who desperately need our help the only way? And by this rationale, shouldn't we turn off all tourist visas, student visas, and stop all naturalization processes? After all, the Boston bomber got here on a tourist visa, claimed asylum, then became a naturalized citizen. That looks like 3 failures, so we should close our doors to everyone?
