South Korea and it’s allies can do the same.

Uh, they do. All the time. South Korea is a US military base masquerading as a country. Nuclear-armed submarines were recently deployed to SK as a show of force. South Korea is a site of missile defense systems that give the USA the ability to launch nuclear strikes and shoot down retaliatory strikes, giving them both encirclement over Russia and China and giving them a path to breaking MAD and bringing us closer to nuclear war.

China is the one who’s going to have a heart attack when there’s even more weapons on their doorstep.

China has been encircled by violent psychopaths for decades. It's not like it's going to be surprised by USA vassal states doing USA's bidding. That's been the state of the world since the USA took control of South Korea from the imperial Japanese and dropped more bombs on NK than all countries combined dropped during all of WW2.

Shit maybe S.Korea should go nuclear as well, really get the ball rolling.

Least death cultish liberal.
