In the past year I've personally raised about $15k USD in funding for Ukrainian military projects with Bitcoin. And I've barely even tried. I could use another 850,000sats for my latest project actually, getting Flash Battalion another van:

On a bigger scale, this is total nonsense. The biggest funders of war and violence right now are Russia and Iran. In both cases their ultimate primary funding source is oil and gas revenue; in the case of Russia a lesser funding source is the Russian government's ability to force companies to simply work for free in exchange for future promises of income that both sides know will probably never be paid. Fiat currency has nothing to do with that, and Bitcoin only fixes that problem to the extent that it allows societies to rise up. But in Russia the population genuinely supports war. That's probably true for most of Iran too. They're infested with Islamic psychopaths. Even if you think the US and other Western countries are the cause of "war", the argument still fails: the US only spends a small part of total GDP on their military. A Bitcoin standard doesn't change anything there.
