Depends what is meant by Ukraine winning the war. IMOObviously the war is hurting Russia and its economy and the people and they are losing alot of soldiers, but Ukraine just has a much lower ceiling in terms of this and will struggle more and more no matter the support they get, its just facts, people can hope all they want but if Ukraine was in a great position and thinking they can actually win the war, Zelensky would not be saying they can't handle another year of war and that the war needs to end this year.

Putin set out to take over the government of Ukraine. If Ukraine it is not overwhelmed and survives as a state, that could be viewed as Ukraine winning (retaining its sovereignty).
