I was thinking the same thing.
If we were to actually get involved, kick it off with an A-10 singing the song of it's people, and eliminate all russian forces in Ukraine in no greater than 24 hours.
If you're not willing to do that then just stay home, we've seen how the 'slow war' style goes.
They say it like that because people are used to being billed in kWh so it gives them a reference.
