the money is taken from education and health care in the US and spent on European defense.

But we ain't got no damn defense over here as we see in Ukraine and furthermore in Iran, with the NATO Military Industrial Complex running out of its wunderwaffen by ways of not having an industrial base to support its military ambitions. The patriots have run out and the newest F35 have no radars or are otherwise already obsolete, and the rest keep falling from the sky or some shit.

both in Eu interest AND in US interest that Eu defense spending increases, war or no war.

Why? How? Sounds absolutely nonsensical. There is no industrial base here to manufacture enough interceptors or jets for this modern stage of warfare, not even crossing into the need for rare-earth mineral mining and refinement capacity (nonexistent, afaik) that these wunderwaffen require, that can be easily countered with enough cheap drones and sufficiently advanced missiles as seen in Iran. All we as European citizens can expect from increased defense spending is an increase in repression (via surveillance tech imported from the US) and an increase in the exploitation of workers.

NATO is a grift and a scam, the military wing of US imperialism with the EU states playing the part of willing vassals in order to get their part of the plunder. Its job is to make the rich richer and keep the poor poor and to kill or otherwise dispose of any and everyone opposed. And yet here you are advocating for the same system in the name of "solidarity"?

I'm sorry if I'm completely off base here, I'm kinda struggling to comprehend your point. I don't believe that increasing spending on one end of the scale would increase the quality of life on the other. The scale is (an integral part of) the system that withholds it from both (and further from people in the global south and other oppressed nations, like Ukraine) and what the people in both ends should do is to work to dismantle the entire system. No war but class war.
