it wouldn't be "two fronts" if you look at the map Iraq and Iran are surrounded by U.S client states. so Iran would only threaten global hegemony at their own destruction. strategically one could take that whole region to be one target. the arguements for targeting Iran were already being talked about on 9/11 itself, former secretary of state Lawarence Eagleburger making his rounds on every 'news" show went on and on about his clean sweep of all potential targets strategy "suggestions". Iran has already come out and warned against strikes on Iraq so it's useless to try to isolate iran, or even appear to. given that it is the stated objective from what we can discern to isolate potential targets 1 by 1, infact this demonstrates that either operation clean sweep is in effect or it's just a matter of employing the nixon strategy of appearing as a madman as no one would fear a reasonable person.
for awhile i tended to think operation: clean sweep is in effect especially after the Peres visit to India but now it appears more like operation: Fear the Lunatic
still it's hard to say for certain but i think that's the whole point...... including iran in the axis of evil is just a means to give the gaurdian council more reasons to step up their suppression of the democratic reform movement, a movement that the U.S. is claimin is "pro western" but isn't. the real threat to U.S. hegemony that Iran presents is democracy occuring only after the U.S. was kicked out. which might present some sort of example for future revolutions in other arab states.
at least that's the way i see it
