I don't know if any Indian diplomats spoke at the conference. However the Azerbaijani ambassador was quite frank that the reason he spoke was to encourage Americans to support his country over Armenia and Iran. The U.S. and Iran, according to him, both pursue the same pro-Armenian, anti-Azerbaijani policy, as the Armenian-American lobby, centered mostly in Los Angeles, is very influential.
Following the Azerbaijani example, clearly the way forward for a Pakistan concerned about Zionists influencing America's India is to build more open links between Pakistan and Israel.
