I suspect the problem is around for a number of reasons.
The Jewish lobby is powerful, so anyone who says the slightest thing they dislike is attacked and blocked (if possible) from public life.
That very thing should wake Americans up as to how much they're being run by a small number of Jews.
The Arms industry love US support for Jew as it increases their profits beyond anything they could expect without Israel's bastard state being around. That arms industry pays off loads of your politicians to keep conflicts going, and Israel is a wet dream for them.
The US press sells papers on the back of good stories, so Israel is great news for them as well.
As long as Americans support Israel, regardless of the $ billions they have to pay out, everyone in power makes a fat pile of cash.
Of course, that kills American when retaliation attacks happen, but what's your brother's life, compared to massive profits?
