Cojones notwithstanding, it is not something to be approached lightly. The consequences could be grave. Problem is, there are no easy alternatives; no clear way out at the moment since the west is dealing with a psychopath. The last thing the china shop needs right now is another bull.

Just like we did before Pearl Harbor, then we joined Europe to fight Hitler, Mussolini and Hirohito. "Let's do it again." Only maybe this time Putey Pu will bomb Wasilla to kick things off, don't cha know.
I think Ukraine could go on to bomb some sections of highways, some main bridges, and rail lines that lead to Kyiv or warehouses in Kursk or attack those convoys ... that would create logistic problems for the Russian forces, then wait for a few days, then switch on to the offensive mode.
