I think it's possible it's a good decision (As with most wars in the middle east, I think hubris is playing a heavy role and we're underestimating the risks involved) but I think I'm in the minority and this is _not_ supported by 50% of my compatriots.

I don't know if by 50% you're talking about left vs right, but I'm center left, and a decent number of center-left thought leaders support this action. I think the people who support this are a relatively narrow 25-30% of remaining neo(lib|con)s in the center, and the more left and the America First right crowd hate this. My guess would be loosely speaking Trump's base hates this more than the typical HN poster. Tucker Carlson for instance will be way more against this than anyone here.
