There's a real problem with governments that invade other countries and attack civilians, and we're in a particularly hot time right now. That gives many current examples, though: should Ukraine prioritize manufacturing water pumps? Or do they mostly need weapons to fight back in the war?
I get that folks don't like war. I hate war. I've seen much more evidence that deterrence produces peace more readily than disarmament. On the flip side, more destructive weapons may be used more rarely, but they kill more people when they are used.
I'm not sure what the optimal approach is, but it almost certainly requires nations to arm themselves in case they are attacked. "Provide for the common defense" was not specified idly.
Ukraine should prioritize making peaceful relationships, as should the Russians and Americans and British - and the rest of the world should be making sure they do so.
That they have not made that priority, choosing instead to prioritize their nations' collective warrior narcissist identities rather than valuing the human life of each, is why those nations are on the brink of destroying each other.
Warrior narcissism is infectious and contagious and insidious. You can see it at an individual scale and you can see it at nation scales, too. The solution is to smash the mirror: deny any and all of the identities involved their right to their own identities, until they see, underneath it all, the true value of human life.
There is no American/Russian/Ukrainian/British identity worth more than the human lives in each state. There is no Israeli/Palestinian identity worth more than the human lives in either state.
The fact that one identity is held as more valuable/important/special than the other, is what gives each the justification (not right) to murder the other.
If the rest of the world had shunned the Russians and the Ukrainians and the British and the Americans at equivalent levels until their identities were no longer of any perceived value, the conflict would not have perpetuated. The fact that Russians clung to the identities of the Russian-speaking humans in the Donbas, the fact that Ukraine nationalist identity took higher priority over respect for human life, the fact that Americans gloat over their own cultural identity of warriors, as do the Brits - is why we have the conflict.
>I've seen much more evidence that deterrence produces peace more readily than disarmament.
Bullshit. Deterrence did not stop a single human life being murdered in any of the current conflicts. "Deterrence" is just warrior narcissist speak for "I've got my mirror, it's bigger than <theirs>, and that is all that matters".
