Was this statement issued after the missile strike on Poland? Cooler heads have to prevail in times like these.
It is reported by the BBC that it was friendly fire. The Ukrainians fired at an incoming Russian missile that missed it's target and hitting Polish territory.
Putin gets a pass on this for now. Article 5 doesn't get invoked yet, but the Allies have to give Ukraine missile defense systems, more fighter jets so another incident like this doesn't happen again.
Thankfully Article 5 doesn't get invoked as additional NATO troops in Poland to protect them from the Russians could/would escalate the conflict ... no telling what Putin would do ...... but not certain Vlad the Invader gets a pass ... if Russian forces don't fire the initial missile, from where they fired it, then Ukraine has no reason to fire the missle that hit Poland.
Ukraine was only protecting itself by attempting to shot down incoming missiles from Russians. But more delay than a pass for Putin. The Allies have to give the Ukrainians more tanks, fighter jets and a missile defense system to keep the fighting within the combat zone
