lol Russia and China also don't want Iran to have nuclear weapons. US and its proxies would just bomb Iran and make them surrender.
Unlike the European and other middle eastern nations, Iran is a tough nation, but they can't stand the wrath of US.
Russia may use Iran in need but it too believes Iran should be put into its place. They may even use the favor against Ukraine.
It would be no surprise if US air force bombs Kyiv next.
