The problem in America is the 2 1/2 century old southern veto in American politics and constitution construction. They wouldn't join the revolution unless the northern rebels agreed not to touch slavery. Patrick Henry's revolutionary slogan in Virginia was, "the British are going to take away your n***ers!".
This neo-confederate version is just the latest iteration brought about by the federal removal of the northern boot from their necks too soon in 1877. The Japan example shows how to get it right.
