He owes the explanation even more to the Ukrainians than to Americans. From Ted Snider at theamericanconservative.com:
Much of the death and destruction was avoidable.

It is no longer easy to tell what the Ukraine War was for. Very early on, U.S. goals got grafted onto Ukrainian goals, and the hybrid braid became hard to disentangle. “This is a war that is in many ways… bigger than Ukraine,” the State Department announced in the first weeks of the war. But, whatever those goals, few of them remain: There will be no NATO membership for Ukraine, there will be no recovery of all of its territory, and there will be no weakening of Russia.
Former President Joe Biden has a lot of explaining to do, as does Ukrainian President Volodymyr Zelensky.
Zelensky will need to explain to his exhausted nation why choosing the path of war over the path of diplomacy after the Istanbul talks in March and April of 2022 was worth the cost. At that time, what still seemed to be the Ukrainian goals—continued sovereignty and the withdrawal of Russian troops to pre-war boundaries—might have been met. Zelensky must explain why he succumbed to Western pressure to pursue wider ones.
He is going to have to explain why pursuing those wider goals was worth the loss of so much life, limb and land. And, if he is to survive politically and, perhaps, even physically, he is going to have to find someone to blame.
He already fired Valery Zaluzhny, who served as Ukraine’s military commander-in-chief until last year. Now, Ukraine’s security service has arrested two generals and a colonel on the charge of failing to protect Ukrainian territory from Russian advances.
