Any leader in a war is “responsible” for deaths. Lincoln, FDR, Churchill. The real responsibility in this war belongs with Putin. The only alternative to fighting was surrender. We know now what Hitler had planned for Britain. He intended to eliminate the entire male population. Those who become prisoners or subjects accept their lot and have no control over it. Those who fight and die do so that others may live.
Not true. I think things could have been worked out far in advance of the fighting, but we did nothing to negotiate and allowed Russia to build their forces.
We wanted this war. There is no doubt about that.
Even if Ukraine wanted to negotiate we would not let them.
