They both have a bit in common. They’re both communist Asian states that the US went to war with during the Cold War and did not win. But the messaging regarding the two states is a lot different. DPRK is treated like the worst dictatorship ever, that kills you and your family for even thinking that the Kims are less than gods, whilst also starving. But Vietnam, they say… nothing.
Why isn’t Vietnam demonized like DPRK?
The more a country is a threat to the empire, the more demonized it is. Make of it that as you wish. Btw did you know that I could have enrolled in several Vietnamese university for my semester abroad, a bit unusual for digital security students.
