As for Israeli power. Israel has huge influence in most western countries. They hold significant sway over political, military and media leaders. For a recent example: when the Israeli prime minister recently went to meet President Obama he attended the Israeli lobby which is the largest lobbyist group in the US and has dozens of senators, supreme court judges, congressmen, and thousands of businessmen and other leaders as its members. Israel can effectively get away with anything even if the President of the United States doesn't like what they are doing (as can be seen by recent events with P. Obama).
Israel is also extremely beneficial for western countries in that it keeps the oil flowing out of the middle east cheaply and securely. This is because the US give billions in aid every year to Israel in the form of advanced military hardware. This causes a power vacuum in the Middle East, forcing nations such as Saudi to purchase similar military hardware from British, French and American companies keeping Western trade in and outs balanced.
There are probably other reasons as well - possibly because the Jewish people are, or have been forced to become, a fluid, inventive and unscrupulous people. Or possibly not. Who knows. There are doubtless clever Israelis just as there are clever British, French, Italian, Russian, Korean, Chinese, American, Iranian, Pakistani, African, etc.
Bottom line is that they were once the oppressed and now they are the oppressors. I have muslim blood in my family and I must say that israel really does make my blood boil and I can understand why a lot of western muslim descendants join muslim insurgents in the M.E when I see some of the atrocities that Israel routinely perform, and the lack of meaningful international reprisals following those atrocities. Makes me sick to say the least.
The M.E is little understood by a lot of westerners. Like for example how the borders and nations we are so used to seeing on the M.E. map were artificially drawn up by the British and French after WWI. The Brits and French back-stabbed a descendent of Prophet Mohammad to the throne of the Muslim Caliphate and split the on a map between them. Most of the issues we have in the world today stem from this. Lawrence of Arabia lobbyied for it not to happen and he actually predicted a lot of the troubles we see today if it was allowed to proceed.
