To end with, the Shah wasn't a dictator, nor was Iran the Terrorist sponsoring nation it is now. And what "despots" who were dictators and/or running terrorist sponsoring countries did our President formally meet with??
========================
The Shah was an unelected, unwanted dictatorial monarch who the CIA and the Brits conspired to put on the throne when they deposed the elected and secular prime minister Mossadegh.
Juniorbush does not "formally" (my what a convenient word) meet with dictators, but he has sent envoys to Uzbekistan and Egypt and sucks up mightily to the government of Israel, that tortures Palestinians, kills Palestinian civilians, bulldozes their houses and holds them without charges or trial for long periods of time, as well as detaining thousands of them each day at border checkpoints for the crime of wanting to work to feed their families.
Besides, Juniorbush was not elected nor desired by a majority of the people of this country.
He is not my president and has never been and when he is gone we will all be better off.
