This country has become so obsessed with political correctness that little will be done, so not to worry.
I expect that this is true regardless of who sits in the White House or who holds a Congressional majority however big that might be. When it comes to caving to outside pressures and vacillating about a response we will be worse than Isreal. The Jihadis will soon find that we are a lot more fun to mess with than Isreal. Reaction on the street might be a bit different though.
