There's a simple solution, which is to listen to
what a majority of our own people believe on this topic and others. Our propaganda tells us that we are a democracy, so this should be natural for us.
Among other things, a clear majority of U.S. citizens support the U.N. - and not the U.S. - taking the lead in peacekeeping and military intervention. A clear majority also support the ICC. I think we'd all be amazed to see just how well behaved our presidents and senators can be if they know they can hang for their actions.
