Would Americans accept if we decided to come here and decide who your rulers should be? So why do you expect us Iranians to accept the idea that the United States shall come in there and decide who shall govern us?Of course, everyone knows that I'm also opposed to the Iranian regime and I have said that we must change the regime. But it is us, the Iranians, that must change the regime.
