Israel is the master inside politics- American Zionists/Neocons know the American Cultural Landscape. They know how institutions work, and have control of first tier of strategic ones. Within the neocon community itself, you have knee jerk tribal cultural loyalty. Thats understandable. What seems mysterious to you is the loyalty of non Jewish Neocons. They can bribe who they need to, make common cause with people who can help them, politically and economically hurt their enemies, blackmail some, control the PR environment and levers of power in both parties, control the envelope of polite political discourse, control the menu of alternative/acceptable foreign policy postures, and buy many supporters who respect international capitalism as the new marxism – the ism of the 21st century– They are good- very very good at it. Most of it is not visible to be public, Every once in a while, like the pardon of Marc Rich, something surfaces to make people say – “whats that all about?” then nobody in the press has the balls to run with it, and the whole thing dies out. What documents did Sandy Burger steal? We don’t know and can’t find out.
The heart of it is that the US press, media, and political institutions are not allowed to harbor any anti Israeli counterweight without being crucified by the media. Who knows what combination of levers and strings control Cheney. National greatness republicans are mostly shallow people who can be persuaded because the “magnificent IDF” is our ally and in the media at least, we stand together for democracy against islamofacism.– crap goes on and on but the point is, every night three hours of sean hannity will glass the eyes over for the person who believes in US excpetionalism. Cheney keeps a picture of Osiraq in his office.

By all measure, American Security would be enhanced by a return to pre 1991 hands off troops out of the middle east, but the poetry of the daring little Israel, standing
for truth, justice, and democracy, and with neat American arms too , allied with US against the hated Arabs and Iranians.— well its just too much for an AEI type to resist. Also there may be other strings and levers that the Israeli call pull on people that we never see.
Bottom line. the Neocon pro Israeli lobby has made it impossible for serious mainstream press or politicians to pull away from support from the militant settler movement. Nobody in the national media will or can do it. China and the Arab oil money are children in this game.
