This podcast argues that Ukraine offers a cautionary tale regarding the two main modern models of force generation. Neither the professional high-tech war model, favored by Western militaries, nor the whole-of-society war approach, said to have saved Ukraine in 2014 and 2022, proved successful formulas for Ukraine. Considering that Ukraine is fighting for survival, with Russian forces inside the country, the failure of both models in action has serious implications for NATO member states as they deliberate their choices regarding future force generation.
