No but without various other enablers the Talibs could not have achieved all they did even if they had the will. That's the point I was driving at.Without strong will to win, do you really think the meager support from Pakistan would suffice to keep Taliban going for 20 years?
Back to the Russians; their troops are indeed mostly unmotivated; not understanding why they are even in the Ukraine. As this drags on however it's not inconceivable that some Russians may adopt the "my country; right or wrong" altitude and will be motivated to fight. Paradoxically as things worsen for them; it could lead to an improvement in the will to fight.
On another matter; amidst all this euphoria about the Ukraine's recent battlefield successes; we should not overlook the fact that despite being weak and overstretched; Russia still has a lot of combat potential left [unlike the Ukraine; Russia is still not even fully mobilised] and this war could drag on indefinitely.
