I am glad Germany didn't stop trading with the US after they invaded Irak by producing fake witnesses, or the second time by fabricating proofs, or Afghanistan.
As an American: It should’ve. If a firmer hand was taken it could’ve saved thousands of lives. France and Germany wagged its finger but basically waved us through.
There was nothing that could have been done from the outside to stop that. The only people who could have made a difference were the citizens of the United States, but about 80% of them thought the invasion was a good idea.
