NATO was not designed to stop this, NATO is an alliance of 30 countries that say if one is picked on, all step up to the plate. Ukraine is not a NATO member. With the supplying of offensive arms I e tanks from a NATO member that could give the Russians the excuse to involve NATO. The supply of ground to air and anti tank weapons are viewed as defensive arms. The rules of war, which on it's self is mad
The UN is supposed to police these situations, but they are a toothless tiger
If this goes the whole way, it will make little difference if you live near a NATO base or not. I live near a defense research island, that won't be around long in that situation.
The war crimes are indeed that. It's a terrible situation that has come about by Western governments turning a blind eye to dirty money etc and a quest for NATO expansion without being honest about the consequences.
