The plan he outlines entailed moving the first 150,000 of them there. It was going to use the surplus navy ships that were no longer needed with the war over.
Only 150,000? Gee, that wouldn't make much of a dent, would it? Didn't Butler read the Mitchell memo? I doubt that there would have been enough surplus ships to get 150,000 people plus supplies over there. And did Butle give any thought to what they would do if those 150,000 people said that they didn't want to go?
