Then there's the other counter-argument with respect to Russia and China - and it's the same argument that was used against Reagan's SDI (when a few still thought some of it might work) and any meaningful ABM system. Namely, that inducing too much asymmetry in specific areas provides incentives for the potential opponents to engage in much riskier behavior, develop asymmetrical first strike measures, etc. Less relevant now than it was 30-40 years ago, but not without any merit (recall the recent Russian announcements regarding their new missile programs).
Increasing warfare precision is always beneficial. It isn't about the belligerents in the conflict, but the civilians in the crossfire and potentials for collateral damage. If technology advances coupled with training reduce rules of engagement violations the people on the ground are the biggest winners.
Even if China does not do it, does anyone else should do it anyway to be on top of China. Do you draw a line anywhere? like should everyone research weapons forever to try to get/remain on top?
My second point is even if you go ahead and do weapons let the people speak and have a debate, telling us that having more weapons is good is dogma IMO, debating this dogma and respecting the people that don't want to create weapons should be a given in a free society.
Although I agree with your general sentiment, there's no need for ad hominem attacks like this.
This isn't a theoretical discussion, because people are already selling combat technology based on HoloLens outside of the US.
Yes it would be better for the world if the US took a more collaborative approach with other regional powers that it disagrees with
I'd further like to emphasize that the idea that the inequality in strength between our military and various 3rd world warlords is a form of injustice is absurd and childlike and anyone who thinks this way deserves to have their opinions discounted like children.
