Are you saying that sovereign nations don't have the right to decide who they're willing to trade with? Because that's in essence what you're saying when you say economic sanctions should end.
They have that ability through the power vested in them by the citizens, to effectively project the force that the citizenry, as a whole, desires to project.
If the citizenry cared, they can do something about that. (They don't, for a lot of reasons. And they're wrong, but they don't.)
If the government acted for the citizenry as a whole, then they wouldn't have to ban these transactions. At best, the government imposes the majority view on the minority. I think that in general this is more dangerous than helpful. Imagine that the government, with full support of 80% of all US citizens, banned doing business with anyone of Iranian descent, not just living in Iran. That's not feasible in the current climate, but it's certainly possible. I think I'd prefer it if such laws were fundamentally unenforceable.
So if country A is at war with country B then the government of A shouldn't be allowed to prevent company C from selling items which materially benefit and provide aid and comfort to country B?
