Do Kyiv Really Need Fighter Jets to Destroy Russia?

There are calls to end the current sort of quote unquote incremental support for Ukraine and just give it all the weapons it needs now. The other major faction I think is the status course who say they're balancing all these needs with the fear of escalation. This war will follow a path that is completely 100% dependent on Western policy. If the West takes a policy decision and says, we will give Ukraine what it needs to win, Ukraine will win. When will be determined by how much the Ukrainians decide they want to expel Russia from their land?
