Do you think gene therapies are developed while the scientists are dealing with food insecurity and competing warlords?
This is difficult to answer. What can be shown is the post-WWII era has been unusually peaceful within the scope of the modern era of nation states. We’re coming up against the century of no great power conflicts of the Metternich Era.
Military leaders have warned for years that one of our biggest threats is our deficit and borrowing money. Every time that the military tries to close unneeded bases and get rid of weapons that aren’t needed, they are thwarted by Congress who doesn’t want to lose jobs in their district.
There is a reason that military weapon makers spread out manufacturing throughout the US.
You might make a compelling argument that us defense spending hasn't helped conflict abroad, but the last military conflict of note on us soil was Pearl Harbor in World War II.
A reasonable person might conclude that us defense spending has been very effective at preventing military conflicts on us soil.
And maybe the case that us defense spending even increases the number of global conflicts if it reduces the chance of conflict at home.
The question isn't if the US defense spending increases or decreases total conflict, but for whom it increases or decreases conflict
Your point still stands though, but I don't think in the way you meant it.
Ukrainian life isn't a threat as much as trivial cost.
Given this priority, it should be no surprise that US military policy results in great death and destruction abroad but not at home.
The US had been supporting Ukraine before that, both by proxy and explicitly (https://www.state.gov/u-s-security-cooperation-with-ukraine/). The Russian invasion was incidental to, not a trigger to instigating, the US support of Ukraine. The over-arching behavior, of weakening Russian influence in a region, has been consistent.
And I don't think the US has had to deploy its full capacity for a long time, not even Iraq / Afghanistan. That's more of a logistics issue though, they could've multiplied their forces and materials but it wouldn't be any more beneficial.

2) Non sequitur? You really believe that spending on war technology (War as in kill-humans-we-dont-like-department) is in no clear way in opposition to spending on health technology? (health as in lets-make-everything-possible-to-make-humans-not-die-department)
Saying US military spending reflects poorly on capitalism is just about the dumbest possible anti-capitalist argument. There is so much more low-hanging fruit. Start with non-centrally-managed monopolies and work your way around various nasty corporate practices from there.
