Of course I have, but I'm also not dumb enough to think personal purchasing is equivalent to foreign policy. I do go out of my way (and spend more) to avoid Chinese goods where I'm able.
Where has it gotten us? Literally the free-est and most prosperous the West (and the rest of the world largely) has ever been. South Korea and Taiwan are certainly better off. Germany, the rest of the EU, and Japan are looking pretty great too. I'm sure Israel appreciated our intervention. Sitting out Rwanda, however, was a bad look, and one of Clinton's biggest regrets.
And when we pulled out of Vietnam there was an unfathomable slaughter in Cambodia. Afghanistan isn't looking to great, but I suppose zero deaths in the year prior to the withdrawal was too high a price for the "no more foreign wars!" crowd.
It's trendy right now to act like our history is some comedy of errors. It's intellectually hollow and incredibly self-righteous to retroactively interpret history in the most negative light. The world is immeasurably better for billions of people as a direct response to US power projection.
"The better part of a century" with American "interventionalism" has been pretty fucking good compared to the better part of a millennium without it.
