If Iran was smart they wouldn't play into Israels game and declare war.
Israel hasn't declared war officially, they want Iran to declare war first so they can say, see Iran declared war on Israel first, they are expecting that response.
Israel already looks like the aggressor, they've always been the aggressors.
The whole world is watching and people already know what tyrants the Israeli leadership has become.
Israel is burning their own bridge with every attack they do.
I dont want my taxes going to Israel to blow people up and start wars with other nations, and pull us into conflicts.
