What diplomatic means should the United States (why the US and not others) take to stop Russia in Ukraine, stop Iran in the Middle East, stop North Korea, and stop China and its support for Russia or insistence of attacking Taiwan?
Certainly there is some room for negotiation and diplomacy and frankly I think we've tried that and tried it until it was clearly insane and then we still tried it. We (the west) tried to invite Russia to NATO and we opened up Europe to Russian gas. We tried the JCPOA with Iran. We have no clue what to do with North Korea. And we pushed for Chinese entry into the WTO only for them to backstab the west.
