With all this talk of "international law", i'd like to point out that these laws are dictated by a NON-MILITARY BODY, furthermore this same body has sat idle in the past during Rwanda, Somalia, Sudan, and the Congo to name but a few. If you follow international conflicts you'll know that literally hundreds of thousands have perished in those conflicts because the U.N. did not act. The U.N. has become a typical bureaucracy. It has so many "checks and balances" that it is simply incapable of acting anymore. Anyone that throws their FULL supprt (I say FULL because I still support aspects of the UN) behind the UN and deems it the answer to everything (whether a War is just for example) is condoning the past mistakes they've made in the nations listed above. In essence you're supporting the mass murders of MILLIONS of innocent people. Think that isn't the case? Well you're wrong. If you deem a War unjust simply because the U.N. didn't approve, then you're deeming that every action in the past the U.N. has not supported (Somalia, Rwanda, Sudan, the Congo) as also being an "unjust" operation. The U.N. abondon Somalia, and who had to go in and save it? The U.S., Canada, and Pakistan. Three nations on the planet stood up and said publically "this is wrong", and ACTED. Once again in the 21st Century we're seeing U.N. inaction. They claim to be all about human rights and peace, yet they won't support the mission in Afghanistan, even though Canada, one of the Worlds most credible" nations is there. They won't support it even though Afghanistan is the 5th poorest nation on the planet and needs more help than the coalition nations can give. They won't support the coalition because we're using Force, even though Force is the only way to ensure the safety and security of Afghanistan. In short the U.N. talks big but isn't willing to make sacrifices to reach the goals. In essence, the body no longer functions.
