You’re starting off on the wrong foot. That’s just Reagan-Bush universalism and everyone who bought into that stupid ideology has been wrong about everything my entire lifetime.
The way you say it, the Iraq War was simply poor execution of a basically sound ideology. To the contrary, the Iraq War was a predictable outcome of the notion that democracy promotion is in America’s material interest, or that it’s worth our while to police borders around the world. That’s a bad idea, rooted in a Christian/post-Christian version of the Ummah and the Iraq War should have discredited that ideology. If you continue to buy into those mistaken premises, a repeat of Iraq/Vietnam/Korea is inevitable.
In 2014, McCain absolutely nailed his prediction on Ukraine 2022. Did you?
This doesn't respond to my comment at all. You're just calling stuff stupid.
For example, the US needs many raw materials and manufactured goods. Our economy is extremely strong because we get these easily and with little friction. Other countries trust our trade deals so they enter into them willingly. And so whenever the US needs a new import, we get it quickly and cheaply. As a concrete example, NVidia gets prime access to foundries and components. Sure, they spend money on it, but our "interests" ensure that the process is frictionless. Any other country would have a harder time.
We also have near universal military access. No other country even comes close. We nearly have permission in advance to go anywhere. If US shipping is interrupted, no one complains when our navy goes and uninterrupted it. In fact we are welcomed. If a US citizen is taking hostage, governments from the area want to help us.
Also, maybe you've noticed that no one is even close to attacking the US. We are so strong that it would be suicide, and that's partly because of our own strength, but also because of our many allies who would back us up.
Finally, we have moral interests. I believe everyone should live in a system based on laws, should elect their own leaders, and should have basic freedoms. The more we spread liberalism and democracy the better the world is.
Sure, you can nitpick about counterexamples. The Iraq war is a perfect example of messing this up. And not every country loves us.
But if you cannot see that the majority of countries are overwhelmingly friendly towards the US, and that we get enormous military and economic benefits, then you are blind.
