Why in front of AIPAC?

I guess I will never understand the political decisions made by American politicians. While I was sitting at home eating lunch and watching CNN International, the US Ambassador to the UN gave a speech indicating that America holds the right to take any phyisical action it deems necessary against Iran if it continues its path of isolation and nuclear defiance. The part that struck me funny is that the backdrop was lined with AIPAC AIPAC AIPAC... Why in the world would the US give such speeches from a lobbying firm that directly shows the American-Israeli ties following all the events both within its borders and outside its borders knowing all of the repurcussions that it may have? I believe that we should give such speeches in a neutral forum or environment to reduce the fodder for conspiracies that the Israelis control US foreign policy. I will try to get a picture of this briefing.. If this bothers me... I can only imagine what my Lebanese neighbors feel.... to be continued..
