Right! Those who whine about 'international law' only mean that things didn't go according to their private wishes.
The only 'international' laws are solemn treaties made between legitimate governments. Anything else is a farce, a lie or a myth. Fact is, we have no 'international government' (yet), hence no 'international law'.
The UN is not yet a world government, but Kofi and his power-hungry pals love to hoist this fiction up the flagpole periodically, just to see how many salute.
