This will rally Russians to quit the Ukraine incursion, just like 9/11 rallied Americans to quit meddling in the Middle East … NOT.
If anything it will drive enlistment and muster local militia.
My view is similar. Ukraine should focus on areas that it plans to recover and hold - emphasis on the hold.
Raids into Russia, unless directly for the purpose of destroying military hardware, are not worth the risks.
Tough enough for Ukraine to recover land to the east or to the south . . . and probably not able to recover both east and south - including the holding.
