Zig,
Should we also blame the UK because they wouldn't allow more Jews to imigrate into Palestine during the 30's, before Hitler started killing them?
Or also Stalin because he was busy killing a lot of them too.
Also, the US didn't start arming the Israelis until the '60's. Up until then they bought arms from France and eastern Europe. In fact, during the late 40's, the US helped UK try and maintain a embargo on weapons entering Palestine.
The UN, in 47, decided to split Palestine between the Palestinians and the Jews. The neighboring Arabs didn't want the Jews there and threw a fit. They also moved in and took much of the land that was supposed to make up the new Palesitian state. When political pressure didn't work, they attacked Israel and lost in '48 and every battle since then. But the blame of the Palestinian situation can also partially be laid at the feet of their own Arab neighbors. This is one of the reasons Jordan has maintained such a tight control of their Palestinian population. In fact, the Palestinians tried to overthrow King Hussien back in the 70's.
You may not be happy with the situation. But is not just the US's fault or the Israeli's fault things are the way they are. Just see my post on world-wide terrorism to see who all the Islamic extremists are attacking.
But, you can never blame too much on Hitler
