LH,

You state:
"Of course the USA has treaty obligations to protect Israel if Israel is attacked. I have no argument with that."

Since a SINGLE nuclear bomb could destroy a majority of Israel's industry and population, you seem to imply that you accept the idea that, after Israel is so severely damaged, the US is within it's rights to inflict the same level of damage on the nation that is responsible. As someone who does NOT want to see a global thermonuclear war, I would rather that we take steps BEFORE that is neccesary, and prevent the initial destruction if possible. Since a LARGE number of the casualties in any nuclear attack on Israel would be Palestinian Arabs, both within Israel and in the surrounding region, perhaps it is those who want Israel to be bombed BEFORE it can take steps to defend itself who feel that the Arabs are not quite human enough to worry about.

If that's what YOU are saying, it speaks for itself.
