Gee, I dunno, maybe because of ISIS, Hamas, and every other fill in the blank islamic wackos targeting it. But then you knew the answer.
Seems like you’re blaming the victim. The terrorists win if they can drive Jews out of Israel, don’t they. Should random terror attacks become a fact of life in the US, where should Americans live. Actually with the exception of 2001 to 2006 there isn’t much difference between the two countries given the large difference in murder rates. Maybe we should all move to Switzerland.
