Sadly, in a country steeped in individualistic "culture", divide and conquer is a particularly effective strategy.
Honestly, that's largely how the far-right has worked in this country, at least since I've been alive. Divide, divide, divide. Make "outsiders" and opposition feel isolated or better yet, make them the enemy responsible for anything and everything ailing the nation. Make up an ailment or few as well while they're at it, why not?
Divided we fall, and it's worked out quite well for those in power, so far.
