European countries are setting up a barter agency for trade with Iran.

It must be humiliating that the US can force them into such contortions. I expect powerful hostility towards the US to follow. If the US is lucky the hostility will follow the bully when he leaves office, but I expect Europe to prepare to be less vulnerable in the future. For instance, it may place security restrictions on the use of US-made parts in weapons, planes, cars, etc.
