Sure; let Russia and Red China share “world police” duties. They’ll leave us alone, won’t they.
South Korea has twice the population and about 50 times the economy of North Korea.
If you want to risk your blood and treasure, go right ahead, but American taxpayers cannot afford it.
I wouldn’t give a scratch of an American soldier’s fingernail or a single Taxpayer nickel to save the entire Korean peninsula from their own devices. Only idiots become third parties in civil wars.
NOT OUR PROBLEM.
