What was the realistic approach needed for the Russia-Ukraine conflict according to the experts?

According to defense analyst Bill Roggio, some form of accommodation with Russia was necessary early in the conflict. He argues that without risking a potential World War III, this outcome was inevitable. The Europeans should have pursued diplomatic compromise sooner, as this represented the best opportunity for Ukraine to minimize territorial losses. Roggio suggests that unless major powers were willing to commit substantial resources and accept significant risks, some concessions to Russia were unavoidable - a pragmatic if difficult reality of the geopolitical situation.
