Beystr jan, I am trying to wrap my arms around the subject but I am afraid your answer fails to show AIPAC's influence in such degree as to convince the U.S. Government in crucial decisions such as this. I guess what I get from your response is that Israel and U.S. are just posturing and they don't really mean what they are saying. But you contradict yourself with another argument for why they might actually do it.
Netenyahu has been trying to convince the world that Iran is a threat to the world that needs to be dealt with, possibly and preferably through military actions, however, with all his posturing and tough talks, Iran is about the only country that he hasn't bombed yet. He needs the Americans to subscribe to this war. This is what everyone is saying. If that is his true wish, then AIPAC would be the vehicle through which to convince the U.S. policy makers to go to war with Iran. Everyone agrees that AIPAC does have a huge influence, but I don't think the U.S. Government can be considered one and the same entity as AIPAC, as you suggest in your reply. The actions speak louder than words.
I don't subscribe to your statement about AIPAC and the U.S. Government being the same entity. They might have lots of common interests, and is some cases, the U.S. defense of Israel has worked against its own national interest, but then again, that can be said about many other U.S. foreign policies in the past and in other regions of the world. I am not a big fan of conspiracy theories. I think that most, if not all countries in the world, have self-serving policies that would benefit their own interest. I just don't see how the U.S. could benefit by going to war with Iran for the sake of Israel and that is why it hasn't happened as of yet, regardless of AIPAC/Israel's constant pressure.
If you think that AIPAC, Israel and the U.S. are one and the same, and that the whole thing is nothing but a show, then why even bother with an organization such as AIPAC? There is no need to lobby if they are already one and the same. Sorry, but I don't buy that.
