First of all, Israel is conducting large scale state terrorism basically since it exists.
Israel was granted its existence by the UN in 1947. The problem with Middle East is that Arabs have never been able to accept that because they don't like Jews. If Israeli Jews were Muslim, the problem wouldn't exist, simple as that. The expansion of Israel's territory since then came in my view in a fair way, as they won one after another defensive war against attacks by vastly superior Arab forces.
Second, some of the worst dictators in the Middle East have been explicitly supported by the US government
So what. It was right to support them when it suited our interest and there was a greater danger to us and to the word to worry about (USSR - the most evil empire in the 20th century). As far as I'm concerned, dictators are a fair game to support or to depose according to our interests and once we defeated the Soviet Union, we are now knocking them out one by one. Saudi royal family has a special deal with the US that temporarily keeps them in power because of oil but as soon as that reason is behind us they will be next in line.
Also, it would perhaps also be a good idea to get a clue at the size the "islamic world" you're talking about, because you talk an awful lot as if it was confined to the Middle East.
And it would be a good idea for you to get some perspective of what a total failure Islamic civilization has been. There is no progress at all of any kind, technological, political or otherwise that happened in any Muslim country in hundreds of years. 2 Nobel Prizes in science by Muslims compared to over 100 by Jews! The best university in any Islamic country (in Turkey, among the least Islamic of the Muslim countries) is not even in the top 200 in the world. Democracy has either failed or been under attack by Islamists in just about every Muslim country. Every border where Islamic civilization meets a non-Islamic one there is trouble, just look at the world map. Israel has shown how to turn a backward desert wasteland into an advanced 1st world country in less than 50 years. Why can't any Muslim country do the same? I think it is obvious to anyone but Western cultural relativists that the reason is Islam.
