And with which country were they at war in the 50s? The US.
No.
First they tried to conquer south (civil war) and were quite successful at first, thanks to Mr Joseph Djugashvili.
Then they were repelled by UN forces, led by US.
Then, after Chinese involvement (apparently Mao was afraid he'd be the next), two Koreas were born.
Since then, threat of invasion has never been real.
If you'd look at the propaganda NK constantly projects on their citizens, you'd see that they are preparing for a US invasion.
First, I don't have means to watch NK propaganda (do you?)
Second, I don't see how on earth it matters. Should I look at what Goebels said to figure what Nazi Germany's intentions were?
And now Trump comes and outright confirms that the US wants to destroy their country. Kim must be incredibly happy right now. It's a propaganda victory for him.
What Trump says and what is going on outside of Korea has zero meaning.
There is no propaganda for NK outside it's borders.
And for inside it's borders, it doesn't matter what's going on outside, that's to begin with.
As for the Trumps words, that goes with "if you attack us or allies" and "if you continue development of the missile/nuclear programs". It's not the same as simply threatening a country. In fact, it's quite different.
But tell me, how does the life of ordinary NK citizens improve if the US starts bombing their country until nothing but radioactive rubble is left? Is that how you imagine American Freedom?
South Korea is how I imagine "American Freedom". And North Korea is how I imagine "Soviet/Russian Freedom".
If you need more examples, Western Germany is again "American Freedom", as opposed to, you guess it, Eastern German "Russian Freedom".
The US is already stuck with two failed nations in the middle east. So I guess it's time to create a humanitarian catastrophe in Asia.
Libya was handled by Europe.
Syria has exploded from inside.(and there are so many stakeholders involved)
The only valid country in this context is Iraq. It definitely was "stabler" with Saddam.
