I've read it. What's your point? Since when did the U.S. sign on to agreeing to World Court decisions? You are the one who needs a lesson in Constitutionality. This is a case of the President stretching just like our courts have been doing, especially in recent years, to promote their point of view. It is truly disgusting.
You need to do some fact checking before you tell someone they need a lesson. The U.S. agreed to ICJ decisions since we created the U.N. and its charter, which includes the ICJ statute. This is therefore a case of compliance with our agreements and, by extension, with our Constitution. Just because you don't like it, doesn't make it unconstitutional.
