You really should think looong and hard about that, because a world without an institution such as the UN would resemble, well, the world as it existed pre-1945 i.e. a world where wars start and then do not end until one country has utterly destroyed the other. A world where two countries go to war and then EVERYONE gets dragged into it, wether they want to or not. Is that what you really want? Really?
