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?
Okay, then why do you think Vietnam warmed to the US and only recently started having better relations than China?
Ideological capture, market penetration, brainwashing, media bias, failure of principled marxist education to be applied in schools. The reasons Vietnamese people like America is the same reason that people in the Philipines and Thailand do. Money and media and intellectual capture of institutions, neocolonization.
