It seems to me that since these ships are landing in our ports and boarding passengers from our nation, it doesn't impact anyone else's sovereignty. Our sovereignty allows us to prohibit our citizens from traveling to our doing business with entire nations (whatever you think of that, it appears to be settled law). Cruise ships would be free to cover up sexual assault for cruises going from outside the US to outside the US. Any potential violation of sovereignty seems less real than the GDPR, for instance. It would be preferable to have meaningful international agreements for vessels, but several decades of experience show that won't happen in any meaningful way.
