That's why I said in the immediate aftermath of the war. Once basic survival was taken care of in the West Indies, a task requiring a year, tops, our intrepid British sailors had 14-24 years of nuclear fuel to sail around the world looking for useful things like HMS Victory, USS Texas, and records which prove the rightful reign of the king they crowned on the boat. The political stability, morale and legitimacy that a proven monarch would provide would be invaluable. To say nothing of the help he could provide in using royal prerogatives (essentially unlimited at this point, as all the apparatuses of administering statute law are gone) to restructure and adapt the West Indies government to its new, sovereign level.
