We've also seen what happens to socialist countries that don't have a nuclear deterrence. Libya made the mistake of dropping its nuclear program to improve western relations, and has been reduced to rubble as a result. DPRK's nuclear deterrence is the only reason why the US hasn't dared to invade it yet, despite the regular "military exercises" near its border in occupied Korea.
In a sense, countries like the DPRK and Cuba are biding their time for when US sanctions lose their effectiveness as US influence declines with the Global South's rise.
Damn you really destroyed their comment there.
