Wars rarely follow straight paths from beginning to end. Belligerents constantly shift, seeking advantage and adapting to change, and the interaction takes its participants to places unimagined at the war's inception. Such has been the case for the American' war in Afghanistan. The U.S. started with clear strategic aims: defeat al-Qaeda and their Taliban hosts. Within months, military action had accomplished both. Yet, having achieved those aims, the war continued to escalate, and the war deviated from its expected path.
President Putin made three foundational assumptions in launching his war against Ukraine that should have been correct but were not. First, Putin assumed the invasion of Ukraine would be a quick and easy fight. Second, he assumed the world would denounce the invasion but tacitly allow it. Third, Putin assumed the war would deter NATO expansion.
