Nobody should want war. We all know what war means: pain, destruction, economic crisis and then rebuilding a devasted country.

The best thing is always say no to war (with some exceptions of course)

In this case if the USA will make war against Iran I'm pretty sure Russia and maybe China won't be happy...and this situation could cause a world war (maybe a nuclear war, who knows).

Why don't they talk each other: USA, Iran, Russia and China could meet and talk and maybe find a satisfying agreement for all of them
