Very possibly. Zealots are like that. The last Japanese soldier didn’t surrender until 29 years after the war was officially ended. He surrendered only after the Japanese government found his previous commander and flew him to the Philippines with written orders to formally relieve him of duty and return to Japan in retirement.

Yep. The whole “island-hopping “ campaign was about blockading Japanese troops on islands in the Pacific so the Marines didn’t die rooting out zealots. Reasonable people would have seen they were losing and surrendered to avoid bloodshed. But the Japanese out waited the Americans and eventually the American President had enough - and there went Hiroshima and Nagasaki.
