I disputed the relevance of this claim, not its veracity. I repeat: how does this make Iran responsible for Israel's actions? If the neighbour to your left doesn't like you and tends to help the kids of the neighbour to your right to lob crabapples into your backyard, but you beat up the neighbour to your right with a club donated by your overseas friend, does that make the neighbour to your left responsible for your action? Should the beaten-up neighbour to your right blame you or the neighbour to your left who appears to have been correct all along about how crappy you are?
There is a factual basis for claiming Iranian material support of Hezbollah. As of now, all we have is Bush Administration rhetoric as the basis for the claim that Iran is behind the Iraqi insurgency. I assume the point you are trying to make is that Iran is responsible for Hezbollah's actions against Israel from within Lebanon and this justifies Israel going to war with Lebanon. Somehow, this is supposed to provide support for the claim that America should go to war with Iran because Iran is nonsensically aiding the Iraqi insurgency's actions against America within Iraq. But if you really want to make a coherent argument, you should say that Israel should have invaded Iran. After all, you are trying to claim that Iran is responsible both for Lebanese resistance to Israel and the Iraqi insurgency.
