The UN had nothing to do with Operation Enduring Freedom.
The US put together the alliance, not the UN.
Then again, why would the UN ? After all, Afghanistan is a UN Member Nation. But wait, so is the US.
That is the whole point. Once an alliance encompasses everybody or a large portion thereof it looses it's effect. Especially, when member nations are waging war on other member nations. At that point, nations chose sides based on previous alliances and the UN is therefore pointless.
For example:
The following nations have sided with the enemy:
Iran
Iraq
The following nations have sided with US:
Britain
Pakistan
Canada
Australia
There are 189 member nations of the UN. 4 have taken sides. Many others are trying to act nuetral. Of the 6 that took sides: 4 took our side and 2 the Afghani side. But, guess what the 2 that took the enemy's side are both Muslim nations that have always disliked the US and 3 of the 4 that took our side were US allies before the UN existed. So, why are 182 nations sitting on their asses doing nothing if this is an alliance. Also, whose side are they going to take. After all, both sides are member nations....
