Russia loves using this logic, which is completely bonkers. Just try to think from time to time?
Now what's important is when some region has mere fractures of a percent vs when its something like 25%. If your country has 25% Russians and you oppress them - I think Russia has obligation to defend them.
That's exactly what it is and I have no idea what sort of insane, convoluted logic you use to come up with any other idea.
but then it turns out that its arms can be used OUTSIDE of that block
Ohhhh, I see. You believe that defending from an invading force means that you can't attack anything beyond the border? So Russia could just build an ammunition factory right across the border and Ukraine is somehow morally bound not to attack it? Completely insane.
First NATO expanded, and then Russia started defending itself on the territory of Ukraine.
I think you are either trolling or just have bugs in your logic.
Anyways, as fun as it was - I think it's time to stop arguing, it's as useless, as always. Everyone applies double standards (I probably do so too, unfortunately), no one's going to change their position.
