As an American I always feel like any writing any literature about sanctions failings would be seen to be providing material support to sanctioned people, which is a crime.<p>This chills my speech and I wonder if that crime is actually constitutional as currently implemented. Article II of the Constitution makes it constitutional for The President and Congress to enter into treaties which may have otherwise unconstitutional aspects - such as international sanctions - but would be constitutional by Article II if the supermajority passed the sanctions treaty. I wonder if the First Amendment overrides that because it was introduced later.
