>What authority? Military occupation authority?

So Japan was justified in exporting Korean women as sex slaves because they occupied the peninsula? If your analysis begins and ends at might makes right, I really don't know what to tell you.

> Soviet even directly rejected UN's proposal.

Why?

>There's nothing can be done at the moment.

The US did not have to occupy korea. They did not have to outlaw the PRK. They did not have to install Rhee, who would go on to block reunification. They did not have to commit war crimes at Jeju. They did not have to air strike refugees at Nogeun-ri

>Talk about dictator, you know Kim Il-sung a dictator too,right?

Not particularly, no. The DPRK largely absorbed the PRK in the North, and there isn't much of any evidence to show that the election of Kim faced faced significant malfeasance. The same can't be said for Rhee. The 1948 South Korean Assembly election can hardly even be called such, considering how voting was held in the same manner as under Japanese colonial administration, where only landowners in populous areas could vote, and where single elders voted for entire villages.

>Millions of death or exile cause he want to "unify" Korea by war

Why did Kim want to unify Korea? Because the partition of the peninsula was facially illegitimate. Koreans clearly did not want it, seeing how they never voted to partition.

>He wants to be another Mao as he won the Chinese civil war. Do you know he purged the leadership of southern communist after PLA retake Pyongyang for him? And then he purged pro-soviet and pro-sino members to make his Kim dynasty.He called them spy from the south lul.

Narrativizing isn't going to get you anywhere. The USMGIK banned labor organization and the PRK. Rhee eradicated an entire island of opposition

>Both dictator was shit,but guess what? South nowaday is better than north thousands time.

Surely that has nothing to do with South Korea receiving the equivalent in US funding of several Marshal Plans, while the North received more bombs than the entirety of Europe during the second world war. What's the union situation in the South today?

Leaving the peninsula to its own devices and governance surely would have led to significantly better outcomes for both halves. The North wouldn't have been bombed to rubble and the south would have stumbled upon an at-least-vaguely stable leader far sooner than it has

>Even if US want to consult with PRK, do you think PRK wouldn't listen to Soviet?

Did the PRK have some supremely endowed obligation to not listen to the soviets? Considering the structure of the PRK, it almost surely would have aligned with the USSR, hence why the US spent so much time and effort installing a dictator in the south, smashing popular dissent in the south, and aiding and abetting in it's atrocities
