The "law" respecting sanctions has to do with the entity that imposed them, the UN. The World Bank may have some loans with conditions and obligations in the event the borrower is taken out. Those would be a matter of contract, and the venue to resolve any disputes would be spelled out in the contract.
But keep in mind Mao's saying, all power flows from the barrel of a gun. Somebody has to enforce the contract with the use of force. Right now, the USA holds that hand.
Another thing I've heard mentioned on these threads was that the money for the food for oil program for Iraq is held in a French bank? Something like 40 million? Is that true? Or did I misunderstand? I'm just trying to figure out how France, Germany, and Russia are going to try and worm their way into the post-war plans.
40 billion, nine zeros after the "40." France, Germany and Russia share a dilemma as to how they will assert their interests in the wake of USA military success, and USA inclination to turn country over to Iraqis. The first venue these wankers are using is the UN, but as we have seen, the USA is not keen on UN dictates. It'll be interesting to watch this unfold.
