The US no longer uses its army for defense. Nobody in their immediate region dares attack them, they're too powerful ("Godzilla", in the words of John Mearsheimer). All the wars that the US has fought since WWII are nothing to do with defense. Just look at the Wikipedia article on "power projection":

https://en.wikipedia.org/wiki/Power_projection

The leader image is ... a US aircraft carrier (the USS Nimitz). That's what the US uses its military power for, to influence events in lands far, far away from its territory.

But, now, tell me which one of the many wars that the US has fought in after WWII did not end in disaster. Afghanistan? Iraq? Korea?

There was a meme doing the rounds the other day: "Name a character who can defeat Captain America". The answer being "Captain Vietnam". The US has faced humiliating defeat after humiliating defeat while bringing death and destruction and immeasurable misery to millions around the world.

That is what HN users seem to have an "anti" sentiment for. If you watch the news you'll be able to tell that this goes far beyond HN. The whole of US society seems to be extremely tired with those "forever wars", those senseless excursions to faraway lands, that not only do not secure US interests but turn world opinion more and more against the US. Even the US' closest allies now fear the US: vide Greenland. Anyone with more than a video game or comic book understanding of how the real world works would do well to be concerned.

Edit: also from EU, btw. Greek but living in the UK.

This is the main thing I would disagree with, as an American who rubs elbows with conservatives quite a bit.

A large amount of Republican and conservative Americans want war. They're primed for a war they haven't had this generation. There are a lot of relatively young conservatives who are eager for war. A weird number of Republicans don't think we lost Iraq or Afghanistan, or a few other wars, so they aren't tired of it yet.

Like 15-25% of Americans also believe in some form of the end times prophecy involving Israel. I'm not kidding about this. The number really is that high. A lot might not openly state that they believe in it, but they were raised under a religious teaching that says it will happen. Hegseth, literally, has a crusades tattoo and openly talks about eradicating Muslims on his weekly or monthly sermon.

But yes a majority of americans, like 60%, are extremely tired of ongoing wars. But I can also drive to towns in the western US where trump still has majority support and they will openly say they support the Iran war. America is really polarized and a lot of conservatives only talk about this stuff to family now.

I grew up super rural and have to deal/work with very religious conservative Americans often enough. There are a lot more of them than people think. They've just learned to self-segregate and keep to themselves and say things a certain way.
