I know many folks have been worried about visiting Israel with civil war raging in Syria next door. By and large, the war has not affected Israel. But just in the last few days, it has come to the Israel border, near a place we visited in 2008. A picture from that trip and one off twitter from a few days ago.
I would still NOT hesitate to visit Israel. This is a somewhat remote location. But it's likely to be off limits for some time.
