<<The Present Iranian Regime is not 200 years old , they have involved themselves in one war that amounts to one third of their entire history and are now involveing themselves in two other wars with proxies. >>
Oh, shit, if you want to count proxy wars, then I hardly know where to start - - El Salvador, Afghanistan, Guatemala, Bay of Pigs, Somalia, Belgian Congo . . .
<<Do they actually have a need to controll the events in Lebanon? >>
I think you're confusing them with Syria, aren't you? Syria historically intervened in Lebanese affairs ever since the French and British carved Lebanon out of Syria so at least one state in the area could be dominated by Christians.
<<Do they have some choice other than to supply insurgents with American killing bombs?>>
Yeah sure, they could stand around and watch while an army of Americans invaded their neighbour, raping, torturing, murdering hundreds of thousands of good Muslim men and women and locking up dozens of thousands more in midnight raids to be abducted and tortured in secret. They elected to do what good neighbours do, help their neighbour fight off a foreign invasion. You'd help Canada fight off an invading army from the Middle East, wouldn't you? Well that is exactly what the Iranians are doing for the Iraquis. They deserve a medal for their actions rather than the endless stream of vituperative abuse that passes for reporting in the American MSM.
