Where US foreign policy failed was after the Cold War. The US failed, I don’t think with any malice, to engage Russia as an equal and give it a greater role. Russia was desperate for it - indeed Bush muted inviting Yeltsin to join NATO under a different banner I think. Disbanding NATO due to the adversary nature of the name to Russia and creating a similar role with the European security council with US and Russian involvement would have been ballsy but given us a new history. There was a small window, the US failed to capitalise on the Cold War peace, Gorbachev was under pressure from the hardliners, Yeltsin projected a hardline domestically but was desperate to be seen as an equal and join the club, our clubs. Two Russian presidents the US didn’t engage properly. The result is someone like Putin.
