Colleagues of ours returned recently from a tour of Israel. They were escorted EVERYWHERE by both Israeli military convoy escort personnel and private security guards with M-16's and Uzi's... on the busses, in the restaurants, in the hotels (except for the rooms - and THOSE were swept by explosives sniffing dogs 3 times each day), on the guided tours and to and from the airports. With all of that, they STILL didn't feel safe and were glad that they left when they did. A suicide bomber detonated herself in a market area that they had been in two days earlier.
Just goes to show that international terrorism is alive and well and is funded by and perpetrated by those who would rather see democracy, including Israel, be destroyed. We either take it to them where they live, plan and hide, or we will be battling them here on our US streets... again... remember September 11, 2001 !
