We should save no part of the U.N. Lets get the facts straight, the U.N. is a 'beauracracy' the longer that beauracracy is allowed to grow or "reform" in order to "strengthen" it the more dangerous it becomes. How long until the U.N. itself is the entity which begins world war 3. Imagine this: A man has just allowed everyone into his house, be they murderers, drug dealers, whatever... he allows them to run wild... for a time... Sooner or later UNSG is going to start giving order.
Understand also, the U.N. has not ended any war. The U.N. is itself, a theater of war, thanks to the allowance for nation's to become members who were not "united" with the principles and spirit of the organization's founding. In conclusion, the U.N. failed as an instrument of peace because it provided no incentive for its member nation's to improve themselves prior to membership. Imagine for instance, that the U.N. required each prospective member to ratify and adhere to the UNDHR prior to membership. That would have push many nations which desired membership to push democratic reforms in order to have their voice heard in the General Assembly. Instead, the U.N. failed due to a very familiar occurence that we are all aware of....
Analogy: Imagine that you are in a Civ 3 clan. Which clan would you prefer to be in, one which the founder asks every person on the planet on to join, or the small closely knit elite clan which know eachother's every move? Well?
Exactly. The U.N. failed as institution for that very reason. It is time that the U.S. begin preparing for a post-U.N. world. Belief that the U.N. is necessary to end war is ****ing stupid. We've already discussed its G.O.O.D. successor which could easily fulfill the forum. The U.N. failed, and now we must come up with something superior. The U.S. should not lower itself to the level of the U.N.
In regards to your weapons, we now have airborne laser missile defensive systems. As for Sydney, the United States is an eternal military alliance of free, sovereign, eternal, and independent states... Like Texas.
