thanks again
It is similar to our sanctions on Cuba. We do not trade with them, but everybody and his brother does. The only difference is that with Cuba, they have little to trade except cigars and sugar, so our unliateral sanctions are more effective, since our tourists pretty much stay away. With Iran, they have oil, and so other countries are willing to trade with them.
Suggest to your husband that he never argue with a fool, lest some bystander think they are are both fools. I've learned that, unless you think you can change their minds, which is unlikely, because liberals have a different world view and values, or you can influence an audience, arguing with a liberals is a waste of energy and leaves one feeling angry and needing a bath.
There are not multilateral (UN Voted) sanctions against Iran.
The US sanctions on Iran are unilateral.

The US is pressing the UN for international sanctions.
