What I'm missing is that as one by one middle eastern countries are stomped to the curb, finding a balance between the countries gets harder. The more functional countries there are, the more room for negotiation, realignment, factions, and thus stability. We should want a muddy mess of interlinked allies. If after Egypt, Lybia, Syria, Iraq now Iran gets stomped, it's easier for the remaining powers to swing hard left out right instead of to continue muddying forward.
