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.
I wouldn't be so sure. Putin has threatened to help Iran get nuclear weapons.
Iran is one of the biggest suppliers of Russia in the war against Ukraine, so IMO they both need each other and if Iran can redirect the attention of the US from Ukraine it's great for Russia.
