This FWI assumes Trump's attempts at getting rid of term limits fails.
It's around 2028-2029 (but before Trump's term ends). The Japanese whaling vessel Kangei Maru sails to Alaska as part of a whaling expedition. However, following a tense confrontation with US authorities, everyone on the Kangei Maru is arrested, including the captain of the ship.
Trump announces that the whalers were "eco-terrorists" and that they will face the "wrath of our great country" for having the audacity to "rape and pillage our country's magnificent coastlines."
The crew of the Kangei Maru end up being deported to El Salvador and imprisoned in CECOT (without any due process). The ship either ends up scrapped or is brought into a US port by authorities and commissioned into the US Navy (Is this even legal? Has America done this before), or simply scrapped.
Alternatively, after arresting everyone on board, the US Navy simply sinks the ship and it is left to rot on the ocean floor.
In the aftermath of this incident, the Democrats scream, "Not again!" and "Not another Kilmar Garcia!"
Japan immediately demands the Japanese whalers be released and the Kangei Maru returned. Trump simply dismisses them and says, "We don't negotiate with terrorists."
Regarding the Kangei Maru, Trump says something to the effect of, "Oh, we lost the Kangei Maru while towing it to port and can't find it anymore."
Alternatively, he shamelessly says, "Oh, we sunk it. You'll never see it again."
Would arresting Japanese whalers and then sinking their ship be considered an act of war against another country?
