> If Iran stopped chanting "Death to Israel"

It's a stupid slogan because it gives politicians ammunition, but it can be interpreted various ways. For example:

Ali Al Bukhaiti, the former spokesman and the official media face of the Houthis, said: "We really do not want anyone's death. This slogan is only against the intervention of those governments [i.e. the United States and Israel]."

Meanwhile, if you judge a country by it's actions rather than it's slogans tell me how Israel is looking right now on the "death to ..." scale.
