For the first time since the 1980s a U.S. nuclear-armed ballistic missile submarine (SSBN) visited South Korea on Tuesday, as the allies launched talks to coordinate their responses in the event of a nuclear war with North Korea.
That would've entailed a full on war with China. Which some people - most notably MacArthur - were ok with. I think his plan involved nuking as much of the PLA as possible.
Personally, I think we should've done some version of Operation Unthinkable and eliminated the USSR. Alas.
North Korea, which test fired an intercontinental ballistic missile (ICBM) last week, condemned the NCG on Monday for "openly discussing the use of nukes"
That's rich coming from NK. As if they don't threaten this on a quarterly basis.
