I kind of agree with you here.
Mainly from the aspect of bullets flying past my head. I don't much care what the "made on" label says and don't really much care the nationality of the person firing them. I'm not sure why it matters other than Russia is being supported by a league just as Ukraine has outside support.
My confusion is why NATO has allowed Russia to dictate the rules and support that is given to Ukraine. So if North Korea wants to throw troops in Ukraine then we should have no problem when France or Poland does the same.
