Would Iran be willing to stop anti-US and anti-Israel propaganda?

Iran would surely point out that Israel isn't allowing Palestinians to govern themselves, and the US would point to the violent suppression of Iranian protests. (And then whatever the hell is going on in the US.) So it's not really clear if anybody is really being allowed to govern themselves.

I don't mean to both-sides this war; Israel and the US are clearly the aggressors and clearly in the wrong. But this is a very longstanding conflict and I don't think a one-sided promise to give up propaganda is going to help.
