My point is there is nuance to the question. We have a dilemma. We need the very tools of oppression to resist the oppression. However, if we arm ourselves with them, we have the temptation of using them to oppress others, to our benefit.

Ukraine gave up its tools. It gave up its nukes, in exchange for an agreement that Russia wouldn't attack it, and the rest of the world would back them, if Russia broke that agreement.

What we need is a balance. The world, as a whole must be able to suppress a violent state. At the same time, no one state should have the power to suppress a large proportion of other states. This would allow for policing action, but avoid the use of force for selfish reasons. Right now, America has the biggest stick. And it uses it, and its threat regularly. However, if it just gave up that stick, others would take advantage of the power vacuum. Collectively, we need a big enough stick that no-one can threaten the collective. At the same time, individual members shouldn't have too much power.

Ironically, this is playing out in Ukraine. While America is sending significant resources, it is not the only one doing so. Abandoning Ukraine would be a dereliction of our agreement to back them. It would also embolden others to act, since Russia got their way.

If you've not ran across them, look up Nash Equilibriums. It's what is in play, and why simple fixes just won't work
