putin /ukraine

i tend too stay away from the topic of politics on similar worlds but can anyone tell me why putin and russia are getting worked up over these missiles. granted it an game changer as ukraine can now hit militiary sites in kursk and other parts of russia that are responsible for weapons used against ukraine . putin has been pounding ukraine now for nearly three years killing innocent civillians for what . the west has been supplying arms too ukraine of different types right through this war . hypocrite putin has been getting arms from rogue states like iran and north korea maybe not as technically good as the the ones the west are arming ukraine . even belarus an putin ally has stayed away from getting directly involved by giving putin troops but that idiot in north korea has given putting arms and soldiers
