Seriously. The United States just sent nearly $60B to Ukraine. Nearly 18 times more than this. If humans weren't so intent on fighting with each other and instead spent that time, energy, and resources on advancing as a connected society, we could do amazing things. Instead, we're barreling into the future as predicted by RoboCop.
You can't just cut keeping tyrants at bay though. I totally agree starting a war is stupid, but defending against invasion definitely isn't. And it prevents future wars from starting or spreading. So as cool as it would be to invest trillions into space exploration, we can't just leave Ukraine out to dry.
I totally agree with you, I'm all for funding Ukraine's defense. It's just my idealist fantasy that everyone one day wakes up and realizes we're being collectively quite stupid for the benefit of a very small segment of the population and we could do so much more if we cut them out.
