I’m sure the US and allies will make that happen. This isn’t Afghanistan - even if the Russians occupy the Ukraine we will be supplying the insurgent forces with technology that will make the Russians feel like they’re fighting the Martians.
Would be nice if the West supplied Ukraine with all this technology before the war began in the 8 years prior - their airforce and Air defence are tiny and dated.
So far the rich nations of the west mostly left Ukraine to the wolves - supplying only short-ranged squad level weapons and dated equipment.
Ironically that train of thought is what is hampering Russia now, since their actions seem to communicate an expectation that they would have been able to just walk into Kyiv like they did for Crimea, and didn't expect the actual resistance of an army fighting for their home
Afghanistan was the USSR’s Vietnam, so I don't know why you'd say this isn’t Afghanistan in this context.
