I;m pretty sure the U.S. never declared war on either of the Korean countries.
As to the 1st WW ending in 1990 or whatever, because that is when the reparations were finally paid off, what a lot of hooey. I guess I would not have visited Germany before 1990 had I known we were at war with them. Why did neither of our countries issue a travel advisory?
