Is the EU a State or not a State in the international sense?
I know it is not a State in ICAO because I looked at the list but how can a State (like the US) have an agreement or treaty or whatever with something like the EU that is not a State?
If the EU is a State fine, then they get a vote and conclude treaties and agreements and the states that make up the EU don't make treaties or international agreements any mre than Nebraska or Ohio do. If they are not a State then they don't get a vote and don't make agreements or treaties.
