It does seem that in retrospect, both campaigns will be seen as in effect having "marked time" -- by shifting the narratives, and forcing the respective occupiers to pause to notice (in a brutal and embarassing fashion) that the clock was ticking on their optional neocolonial projects.

Tet also had significant political impact, and forced Westmoreland to start reevaluating the cost (and manpower) needed to keep the ball rolling.

As to whether Kursk '24 will portend something similar for the Russian side - time will tell.
