Why would they not attack things in Poland?
Because they would certainly suffer the consequences of such an escalation.
The rules (treaties) are maintained by fear, not ink.
But isn’t Ukraine by intentionally shipping items to NATO to be repaired ALREADY involving NATO and as such making NATO a potential target by NATO’s own approval?
NATO is purposely and intentionally inviting an attack JUST so they can say “SEE SEE we were attacked” giving them just the “excuse” needed to attack Russia. Gulf of Tonkin sound familiar?
At some point the Russians will get sick and tired of NATO having an indirect hand in the conflict and choose to blow one of these repair depots “outside Ukraine” to hell.
