I know this response is a bit long but please read for my genuine response to your well reasoned post.
Not so fast I don't necessarily disagree with what you are saying. I am old enough to remember the true fear of the cold war. For some strange reason it was widely accepted that if the Red Army launched a nuclear missile at us we would be safe by simply getting on the floor placing our arms over our head and crouching underneath our desks (how ridiculous does that sound now LMAO) But Russia will always be the evil empire to me. I to respect the "punch the bully in the mouth" mentality. I vividly remember the miracle on ice. I remember that game was not for the gold medal. We had amateurs playing against grown professional men. I remember President Reagan saying "Mr Gorbachev TEAR DOWN THIS WALL!" Then watching as Mr Gorbachev did exactly as he was told. I remember the jubilation at that insanely symbolic victory in the Cold war.
But as I have aged I have also learned that the cost of fighting another countries civil war has absolutely zero benefit for the US. Doesn't mean I don't have empathy for the people who are affected. It's called perspective. I have many Laos people who work for me with harrowing bone chilling stories about packing only a few things and trusting strangers with taking them from the only home they ever knew to the hope of just a better chance of survival. And these are some of the most amazing people you can ever imagine to have met.
Look at the # of casualties combined in the Korean, Vietnam, Iraq, and Afghanistan wars ( at or around 100,000) and I ask you one simple question looking back now was it worth it? Are any of those countries better off because of our sacrifice?
Apologies if my takes have inferred anything other than my steadfast distaste for the MIC of our country and the propaganda they have pushed resulting in countless heartache for US family members for roughly the last 75 years. I am as conservative as they come I don't hide that. I also have zero use for the Bush, Cheney, McConnell, Graham, Romney wing of the Republican party.
I appreciate your feelings and I bet we are probably way more together than you may realize.
Korea is definitely better thanks to us, the South at least, the ones we helped; you can see what help from the Chinese gets you.
Vietnam is definitely a better place now too,but that is despite what we did.
Iraq has had some improvements, they dont have a leader gassing their own people, and the quality of life for the minorities has gone up considerably. That may be a wash with the violence that came after we left.
Afghanistan it's hard to say one way or the other, doesnt seem like anything really changed.
The outcome for the locals isnt how I would judge worth. The outcome for us is what I would look at. So in that case it would be three no's and a yes, korea being the yes.
But then you also have the butterfly effect, of what happens if we werent involved in all those conflicts? Not just for the locals, but us and the rest of the world. Despite us being in those fights, and many others, the last 70 years since the rise of NATO, and particularly since the 90s, and the fall of the Soviets, you have seen an unprecedented peaceful period. And I think it's impossible to say that if the US wasnt interfering militarily as we were that that peace would have existed. That peace brought stability, trade, exchange of ideas, which definitely helped us.
Our dominance and enforcement of the petrodollars has absolutely increased our quality of life back home. Our money goes farther than it should on the international market which has untold benefits for us. I think you are beginning to see what happens when our dominance slips. I dont think it's a mistake or coincidence that Putin began this under Obama/Biden, and has come in to finish under Biden/Kamala. We are weak on the international front and you saw a hot spot kick off that probably wouldnt had if we were perceived as being strong. And note Ukraine isnt a civil war, this is purely a result of foreign interference.
