Federalist Nos. 15 and 16 led me to two conclusions. First, Hamilton is accusing those who oppose the Constitution of hoping for a different result by repeating their previous actions (sounds like our modern politics of perpetual incumbency). Second, the confederacy that Hamilton describes that preceded our current (theoretically) Constitutional government sounds a lot like the United Nations – it lacked sufficient authority to effectively enforce its edicts on its members. This tells me that the U.N. is bound to be ineffective until it disintegrates or is replaced by a stronger version of world government.
I’d hate to think what would happen if the U.N. were given better enforcement powers unless it is done with a very firm limitation on what areas of life the U.N. had authority to regulate (as our federal government had at its inception).
