"But Israelis have bought our corruptible political system to the point where all our politicians fight each other to prove who is more of a "friend" to Israel. If the US where acting in its real best interest it would keep Israel at much more of an arm's length. In a way Israel is much more of a dangerous enemy to American democracy than Iran, Russia, China or any other country."
That's a lot more serious than dispassionately noting how one nation among many that has an influential lobby in the United States.
But one other point that is worth considering: American public opinion of Israel is generally around 60% positive, 30% neutral, and 10% negative (source: http://www.jewishvirtuallibrary.org/jsource/US-Israel/poally...). Is it particularly shocking that politicians go where the votes are? No conspiracy theory required.
