This latest action by the Republican 47 is unprecedented and capable of causing international mischief. If Our (particular) democracy is seen to be incapable of entering into binding international treaties and agreements, it would be very, very bad. A couple hundred years of development of a code in which our nations might function, if not always live, we cannot have national legislature's, of any country, threatening to undo international agreements. It just isn't done and I feel like an idiot spelling it out but if nations cannot trust the USA on treaties and agreements, the international order vanishes. I am not sure it gets more serious than this and the fact that our Right Wing is so used to being an oppositional force they cannot be trusted with real power.
