And you want to go to war over it.
DoodleDawg, you've asked the wrong the question. The question is; Do we ignore our ethical and legal responsibilities because they're inconvenient?
We have no ethical or legal responsibilities in this. The Marshall Islands are a flag of convenience. They'll let literally anyone register in their country so long as they pay the fees, and companies are lining up to do so because of the tax advantages. There is no connection with this ship and the Marshall Islands except on a piece of paper. The ship is not owned by the Marshall Islands. There are no citizens of the Marshall Islands onboard. The ship was not seized in the Marshall Islands so they weren't invaded. There is absolutely no reason why the U.S. should intervene in this. None whatsoever.
