Check back in a year, when the Russians have consolidated heir gains and Ukraine is still begging for money. Lots of money.

Will the excuses they used to retreat from Kiev, Sumy, Chernigov, Nikolaev, Snake Island, and Kharkov oblast still carry water with you, or is there a tipping point at which you begin to re-assess the war-fighting capability of the Russian army? In short, how bad do they have to fail for you to reconsider the outcome?
