I think Israel has done alot of bad things, which I am sure that many people here would be more than willing to enumerate. The Palistineans do have a legitimate complaint, which some people in the mainstream media have been too unwilling to deal with. It seems that in response to this opinion by some in the far-right, the left has felt the need to move itself to the exact opposite, perhaps at start because of an actual opinion, but now just as a way to yell at the right.
That doesn't mean I don't at times enjoy yelling at the right, but occasionally it allows Tom Delay to steal the issues from us (as in, when the right says they love the flag, we feel the instinct to say, well we hate it, even though I, personally, and I suspect most liberals do not).
The far-right is convinced that Israel is always right, and the Palistineans always wrong. That is absurd. The far-left is convinced that the Palistineans are always right, and Israel always wrong. That is equally absurd. There is a gray, and it is our obligation as intelligent people to dwell there. Israel has done bad things, the Palistineans have done bad things. Let us criticize both when they fail. The Palistineans have a genuine compliant, which Israel needs to work to answer, yet that it is no excuse for terrorists to bomb innocent civillians, and if they do, Israel has every right to defend itself, no an obligation to do so. The US could certainly have been nicer to the Arab world, and perhaps that might have worked to alleviate some of the hatred towards us. Nobody would argue, though, that therefore we do not have the right and obligation to bomb Osama Bin Ladin and any other terrorist who threatens the lives of Americans. That being said, we should ALSO work to be more internationalistic, so we can stop terrorism at its root, but that does not mean we give up the right to fight the symptoms as well.
Practically, taking morals out of the question for a bit, it would be idiotic for the US to not solidly back Israel. It is the most stable government in the region, to begin with, pretty much the only democratically elected one which is, scarily enough, the least theocratic. Not only that, its assistance to the US military (missle defence, for example) is critical to our defences, and its scientific contributions help us greatly.
In my opinion, we have allowed the Right to decide our views for us. I am a liberal who believes that the US government can and should be an active force for positive change, should assist in solving the perhaps unsolvable MidEast crisis, but should also support Israel, certainly the least bad of the nations, and perhaps the best.
