I was talking strictly about the US. I'm aware that there are actually places on this earth that have a problem with terrorism. The US isn't one of them.
Wow, after 9/11, after the boston marathon, after ricin and anthrax to the president, after the first world trade center bombing, after OKC bombing? These were actual events with actual deaths. These are actual problems in every definition of the word. I understand very well that Israel and other places have more frequent attacks (though few/none have had attacks on the scale that we have) but that does not exclude the US from having a problem.
Do you realize these events are decades apart? We have a terrorist death count of something like 100 people a year. 100 deaths a year in a country of ~350 million people isn't worth thinking about for one second.
