The United Nations is an important part of diplomacy. It's not perfect, but it is something. Abandoning it is foolhardy. Not everything should be settled with brute force, like Republican warmongers would have us believe. Having a congress of nations agreeing to fair international rules helps for lasting global stability and peace. If we leave, we would be asking for trouble: we would lose even more influence than we have since this current administration seized power. A dangerous idea indeed.
