I don't know where I stand on it, personally. I can see the argument that NATO funding should be a bit more proportional, certainly. Equally, the European NATO members aren't going to make up the difference by pulling the money out of their asses overnight.
Where it falls down completely for me is that I don't believe for a second that this would actually reduce our military budget, it'd just shuffle it around. Now, there are absolutely tons of things going on in the "war industry" that, at least from a certain perspective, desperately need the funding. Don't know how much I'm actually allowed to know, but suffice to say that COVID absolutely destroyed the manufacturing sector that our military relies on. I only really know specifics from the naval side (Navy, Coast Guard, units within other USAF branches that do water-based operations), and we're years behind schedule on R&D and production of new subs, warships, etc., and contractors like Electric Boat have been almost completely impotent at filling the shoes of the veteran shipbuilders who retired during COVID in huge swathes. It's left them with far too few workers in general, and even those who are left have barely any experienced engineers around them to learn from.
Combine that with what China is currently doing with its Naval forces, and the sense of urgency becomes so thick you could choke on it.
*sigh*
I just want to get to 2029 without Elon having replaced the dollar with some fucking stupid crypto bullshit.
