Your side had their chance.
You f’ed it up.
Ukraine will suffer for a generation because of the refugees, cripples and dead. Ukraine is an economic basket case (1/3 GDP loss), has a heavily damaged infrastructure, few will really want to invest there even after the war ends (not like 2014), and they will end up with 17% less landmass. Even EU membership well in reach before the war is now lost.
Congratulations.
If you continue the war, Ukraine will simply lose more ground. The longer the war rages on, the WORSE the situation becomes for Ukraine.
Or zElensky could just go home from the White House...
