Russia's use of imprecise weapons systems close to Poland is irresponsible.

what say you now, since we know it was the Ukraine and not Russia that hit Poland?

Poland knows that Ukraine is fighting Russia for them. Russia is attempting to re-establish the "Warsaw Pact." The missiles the air defense weapon that landed inside the Polish border was aimed at Ukraine just on the other side. If Russia was not firing the missiles, the air defense system would not be employed.

To save lives and de escalate the situation, maybe The Ukraine should just surrender

They have exposed the Russian Army for the Keystone Kops Karacters they are. They are winning this war. Russia is running out of munitions and has to rely on North Korea and Iran for supplies. Ukraine is winning this war, to the extent that anyone wins a war. Putin needs an offramp but cannot find one. He could "get really sick," and not want to pass the burden of war onto someone else. Ukraine is in such a strong position that they are publicly ruling out a "cease fire," holding out for Putin to surrender.

Looks like it was a Ukrainian missile that killed those Poles. Should Poland bomb The Ukraine in retaliation?
