Most of your claims are either misleading or outright false. I'll just go through the main ones:

1. Legitimacy of governments: Neither Korean state emerged from nationwide self determination, but between the two, South Korea was way more legitimate. It was recognized by the United Nations in 1948 following UN supervised elections. Those elections were limited to the South because the Soviet Union refused to permit UN observers in the North. North Korea’s government was established under direct Soviet occupation, with Kim Il Sung selected and installed by Moscow. This is not disputed by historians.

2. Kim Il Sung and elections: There is no evidence that Kim Il Sung would have won free, nationwide elections. This is pure speculation. Kim was not a dominant national figure in 1945, and the North itself never allowed free elections. Opposition parties were eliminated early, including before the war. Claiming inevitable electoral victory is propaganda, not history.

3. 38th parallel: You're correct that the 38th parallel was not an official border before the war. It was just the line of demarcation between U.S. and Soviet occupation zones in 1945, but after the war, the armistice did establish it as a de facto border.

4. Border incursions: There were border clashes and provocations by both sides before 1950. That does not change the fact that North Korea launched a full scale, planned invasion on June 25, 1950, using tanks, artillery, and coordinated divisions with Soviet equipment and Stalin’s approval. This is established by Soviet archival evidence. Calling this justified or defensive is an ideological claim, not a factual one.

5. Bombing and “genocide”: The U.S. bombing campaign was devastating and caused enormous civilian suffering. That is true. What is false is calling it genocide. There was no policy or intent to exterminate Koreans as a people. At the same time, your account omits that North Korean and Soviet backed forces carried out extensive atrocities in the South, including mass executions of civilians, political prisoners, and suspected opponents. Brutality in the war was not one sided.

6. Biological weapons: The claim that the U.S. used biological weapons derived from Unit 731 is false. These allegations originated from North Korean and Chinese wartime propaganda and have been discredited. No credible documents or physical evidence supports them, and post Cold War archival research confirms they were fabricated.

7. Postwar “siege”: What siege? 2/3 of the borders that North Korea has are with its allies, Russia and China. It has maritime access to both of them. There's NOTHING stopping North Korea from trading with other countries, the Kim dynasty actively chooses to keep it to a bare minimum even if it comes at the comes of their citizens' well being because they want total control.

8. Threatening to resume hostilities: You sure got things backwards. The reason why the U.S. has a continued military presence in South Korea is because the South Korean government requests it and pays for it. Why? Because the US military acts as the ultimate deterrent to prevent North Korean hostilities. North Korea still actively threatens North Korea with nukes, invasions, and they also occasionally do some minor attacks. For all intents and purposes, the Korean war never ended and no formal peace agreement was signed. The reason for this because North Korea refuses to proceed with talks in good faith.

You are so wrong because you consistently replace documented facts with ideological framing. You treat speculation as evidence, erase Soviet responsibility, excuse a war of conquest, and repeat debunked propaganda. That is not historical analysis. I'm talking history, you're not. Not to mention that your entire thesis here doesn't even answer the central question of this whole conversation, which is why does North Korea have insane levels of tyranny? I'm saying it's a result of the Kim dynasty's evil and greed as other war torn countries did not end up being this locked, isolated, and totalitarian. It is entirely unjustified and the regime is to blame. You, on the other hand, are saying that their tyranny it's because of war that stopped being hot 70 years ago and 9/11. You're not a serious person and that's not a serious stance.
