If Americans perceive that US policy vis a vis Israel/Palestinians (whatever - whatever the heck that situation is over there, which means absolutely nothing to me personally either way as far as I can figure out) is endangering their lives a la 9/11, there will be demands on the pols to change that policy. Once they see it like that, they are not going to put up with getting blown up over a land dispute half way around the world when we have millions of empty acres in the US.
You might want to find out about what is going on over there and what it means to this country. The safety of individual citizens is NOT the #1 priority of your government.
