So he is saying that Iran is not responsible for checks notes Iran hitting ships of third party nations? How old is he, 5 years old?
If the bigger player is not respecting international law, why should Iran? Also, I haven’t heard of any third party country being hit, you might want to share some sources on that claim.

So because the US is breaking the law against Iran, Iran gets to break the law against third party shipping?

You are advocating evil.
