I heard a good interview on the Ezra Klein show that pointed out that the UN Security Council veto is a proxy for using nuclear weapons. We'd all rather that superpowers use the veto than that they use nuclear bombs to enforce their will.
That said, human rights should be the highest priority for all countries in the world. It's too bad they're not for us in the USA, and it's too bad that we are willing to defy the world on that question. Qualified yes.
