I understand how worse it can get. I lived in Germany during the Cold War, and the nuclear brinksmanship was there every day, but even back then they understood NATO forces had to keep the Russian bear in check. My response to you was well written and logical, I have no idea what brought out the knee-jerk ad hominem aside from the fact that I disagreed with you.
Well, at least you clarified that.
War is won and lost through logistics, not just the fight at the front, those of us who served understand this. Those attacks in Russian territory are having a much bigger effect than you may realize and could in the end be critical to turning the war to Ukraine's favor. Constant reluctance out of fear of what Russia might or might not do is a fool's errand.
The SAS have a motto "who dares wins". During WW2, especially in North Africa, they fought hundreds of miles behind enemy lines and wreaked havoc. Ukrainian SpecOps have been heavily trained by US Special forces, Navy SEALs and SAS. Let the hungry dog eat.
