Continued Russian attacks on U.S. or allied "soil or systems" merit a steady roll-back of appeasement-based policies crafted to reduce wider tensions and discourage Russian efforts to expand their invasion beyond Ukraine.
The carrots have failed and it is now time to try some sticks.
Rolling back Europe's informal commitment to keep Western-sourced tanks, aircraft, and other "offensive" weaponry out of Ukraine is a logical first step. Russia only cares about the battlefield if the Russian Army loses significant ground or faces a significant loss.
I think that cyber attacks on government or infrastructure should be regarded as an act of war, perhaps cause for shooting, perhaps cause for cyber-responses; but this treating them as nothing is crap.
