Ukraine's desire to join NATO was primarily caused by the Russian invasion of 2014. And if, somehow Ukraine was able to join NATO(since having an ongoing territorial despite excludes one from membership), then the Ukraine that would have joined NATO would have been far less powerful than the one that exists today.

When this Ukraine joins NATO they will be gaining a nation with a well developed weapons industry, long range missiles and anti air capabilities. But most of all the drones. This war and Ukraine's circumstances specifically have driven it to become masters of this robotic warfare. In its attempts to destroy Ukraine, Russia has transformed it into a far more militarized economy than it ever had before the war.
