once a country of mystery and spices

That comes across as a bit orientalist, friend

Would a nuclear exchange between these two countries drag the rest of the nuclear powers into the conflict?

As part of the constitution that was imposed on them when the US rebooted their government following WWII, Japan can’t activate its military except in self defense.

Their politicians have been complaining about that and trying to get rid of it for decades now, but in my opinion every country should have such a provision. Any sane politician claims they wouldn’t use the military unless someone else attacked first, so why give them the option at all?
