Sanctions grow

I am all for sanctions on the Seyyeds. But we all know that the people on the list from the link below will find other ways. At least the US is trying. Question to ask is why did it take so long. Why didn't we have this list when the US hostages were taken? And why aren't more French companies on the list?
