How didn't we observe the NK's sovereignty when they invaded SK?
We didn't... yet. I was talking about the spread of communism as the blank check that was given to American foreign policy "hawks" to run amok, even using the government against its own citizens (see McCarthyism) and other countries (see VietNam, Nicaragua, Laos, Cambodia,
et cetera). Worry not though because our obedient military is doing, right as we speak, the work of Satan himself, trying to provoke NK into an armed conflict. Right now there are
Japanese spy planes flying over NK taking pics UNINVITED, meaning in clear violation of NK's territorial sovereignty, all being done for the benefit of the you-know-who.
Having said this, I do not think there was ever an invitation from the South Korean people for us to go in there and help them. The entire conflict was cooked up by the UN, approving yet another illegitimate war, one that wouldn't have been approved had the soviets been present to veto the vote to go to war (probably because they were involved in the war too-more assholes). I mean Korea was split up not by popular support, but by forceful action from a second actor. When the war ended, the sane thing to do would've been to carry out elections in South and North Korea. The UN, inexplicably, decided to only carry out a plebiscite to select a South Korean president, so the question of national identity was KNOWINGLY and PURPOSELY avoided so as to create tension (much like Iraq nowadays and it being an "artificial" country: The Kurds are the Kurds and have always been the Kurds; the Shiites want their own territory and so do the Sunnis, meaning the country we now know as Iraq is only held together only by the American presence). This question is still on the fucking table. The majority of North and South Koreans want a united country. Somehow the UN can't come up with the chops to make that happen. Why? No idea.

Is this type of stuff that creates the Kim-Jong Ils of this world? You betcha!
And how did stopping communism help me personally and to who's benefit is it? The more communism there is in the world the less productive, free and progressive the world is.
My question is: How did the war on Communism help YOU personally? Whether the world is "less productive, free and progressive the world is", which is not true by the way, is irrelevant. I am talking about your personal benefit.
For me personally a stronger USA, because of the fall of communism, has allowed me a better standard of life and a safer one. If communism doesn't fall, we are still in a cold war with nukes aimed at each other 24/7.
How has the fall of communism allowed you a better standard of life? Give me specifics. Off the top of my head... one of the greatest economic periods in American history is that from the end of WWII and 1970, when 1 person used to make enough money to buy a house, start a family, put that family through college and enjoy nice vacations overseas thanks to our overvalued currency. Fast forward to today. How can you make such an absurd statement? Furthermore, you keep referring to be living a in safer USA now that communism is gone... yet not too long ago, and for the first time in American history, since God knows when, the US territory was actually attacked. Note:The communist "threat" gone at this point. Moreover, 95% of Muslim radicals want to attack it again and again. So does North Korea and Iran and some other countries.
Yes, America is no saint. We did some shady shit in the cold war. But did we launch a preemptive invasion into NK like we did in Iraq? No.
The Korean War wasn't even approved by Congress dude. There wasn't even a Declaration of War. The whole fucking conflict was carried out like a mob hit. Unfortunately wars kill innocent civilians. Mobsters don't.
