To what extent does the United States and European Union intervening in the aerospace industry go against UN international law?

This is for my IB Extened Essay. This essay question is shown above. Will need to have both politcs and economics involved throughout. Main focus will be Claim-Proof-Counterclaim and why it is important. Make sure to have vaild sources and lots of research evident. Make sure to have a lot of Poltical Theory (a realist would say… or Morganthau would argue..) If you have any questions let me know.
