...Okay ask plainly then. What is the problem you have with my answers?

Are you a free market absolutist who thinks anything that prevents people trading with whoever they like is wrong? I am going to have to disagree with you if you are.

Are you mad that it was a ship from the USA enforcing the embargo rather than a Greek one? The USA does the heavy lifting protecting all international trade routes so, in all likelihood it is the USA who is going to enforce sanctions especially when it is in there interest to do so.

Do you think a Greek company that resides in a country that is also sanctioning Iran should be allowed to facilitate a trade that breaks the law of the country it is based in? The company should be punished for breaking the law of the nation it resides in.

If this was a Chinese company and they used CNY it would have been wrong for the USA to seize the cargo and fine the company but it wasn't so that is irrelevant.
