Bush Junior’s PNAC crew wanted boots on the ground in Iraq because their goal was to take over the country, not just to punish it.
The PNAC geniuses had been insisting that Muslim countries could be converted into western style democracies after a proper beating followed by giving them the vote, blue jeans, rock ‘n roll, and bubble gum.
Their bible was Francis Fukuyama’s “The End of History” and a few other goofball books of similar vein that neocons wrote for each other.
Anyway there is no need for us to invade Iran in order to hurt them. Just keep the Bush crew occupied assisting illegal aliens and other things that they like to do, and keep them away from military planning.
Compelling common sense, as always.
