Trump comply with a UN court? He doesn’t even comply with US courts!
Sanctions havn’t done shit for America in a century. They’ve kept malignant governments in power by denying the one thing that would topple them: exposure to something better. You want to bring Cuba to it’s knees…let the gringos and their popular culture in. In 2 years the place will be the de facto 51st state. As for Iran. They have a very legitimate bitch with the USA that goes back 50 years. You go slow there. That’s what Obama did. Slow. The Clerics will then allow a few iPhones, a few Pizza Huts and you keep moving. Slowly. There’s no good reason to sanction the people of Iran. They are the future. Sanction them and you lose you influence over Iran’s future.
