What are the alternative perspectives in the Ukraine conflict negotiations?

The clip presents contrasting views on resolving the Ukraine conflict. The speaker identifies a 'realist position' as the starting point, which appears to favor negotiation. This is contrasted with two alternatives: either a 'long, protracted Vietnam style war' in the region, or a 'zero sum game' that could escalate into 'World War III' to fully defeat Russia. The discussion frames these approaches as fundamentally different philosophical positions - realism versus idealism - in addressing the complex geopolitical challenges of the Ukraine conflict.
