I understand the desire to not participate in defense technology. But at the same time people need to be realistic about the world we live in. Peace is a matter of good diplomacy backed by military force. You can be a peaceful nation without having a strong military until a country with a stronger military decides they don't want peace with you. At that point, your sovereignty and safety is at the whim of that other country's might. The United States is the world's only superpower and as such is a major deterrent against military action from countries like China and Russia. But those countries are actively pursuing technologies that will change the balance of power in their favor. The moment an adversary gains a capability you are unable to counter, that decreases your power of deterrence. If China attained enough capability to be sure they could prevail against the United States in a conflict over Taiwan, they might take the opportunity to mount a first strike. If Russia thought they could forcibly take back their former Soviet satellite states with no pushback they would. The United States (and it's allies) for all its sins and flaws still stands as a deterrent against the ambitions of several illiberal regimes. It is better to maintain the power of that deterrent by staying ahead of the military technology curve than to ignore nee technologies and get surprised when an adversary develops and uses it against you. We've already sort of seen that with Russia's offensive cyber warfare and social media active measures offensives.
