The person you responded to was talking about the United States' war in Korea:

They utterly destroyed the North of Korea during their genocidal anti-communist war, for example

You responded with:

"This is just like what the US did to my favourite monarchy 75 years ago" - a totally normal leftist response to a war crime happening today

The DPRK, in no way, resembled a monarchy prior to the Korean war, like you implied. The DPRK developing such a centralized cult of personality, and took up it's particular foreign policy positions, as a direct result of US war and occupation.

The US and Israel indiscriminately bombing civilian targets in Iran with the explicit intention of inducing some sort of societal collapse is absolutely comparable to the Korean war.

The response of Iran to dig in its heels, appoint the previous Supreme Leader's son as his successor, and take up such an aggressive posture, is also a direct result of US intervention, and has clear parallels to the DPRK example.

These countries, like Iran and North Korea, are the way that they are, not in a vacuum. Not because They're ontologically evil. But because they're responding to genuinely horrific conditions imposed upon them by the United States.

Whatever we might feel about them. Even if I don't like that the DPRK has developed this cult of personality around the Kims, that fact is secondary to the material reality of what has caused this state of affairs in the first place.

You're not getting dragged in this thread because "Le Stoopid Takies Luv Teh Commie Monarchy!1!" But because you're missing the forest for the trees.

If you actually care about the People of the DPRK, and ending the Kim's cult of personality, then you should want a formal end to the Korean War, the withdrawal of all US military assets from the peninsula, and for there to be UN mediated talks between North and South Korea about how they might be able to integrate, politically, socially, and economically.

Similarly, if you actually care about the people of Iran, and the wider middle east, you should want an end to this war, withdrawl of all US military bases from the region, the dissolution of Israel, in favor of a multi-ethnic Palestine with right of return and reparations for all Palestinians, and a laying down of arms for all Iranian-backed non-state actors who would no longer need to fight in the absence of Israel.

Complaining about Tankies online does none of this
