The answer to whether World War II is responsible for the current global orders depends partly on how you define current. World War II probably was responsible for the global order for the last 70 years or so. And, certainly actions taken by Russia and the United States during World War II are responsible for the divisions that currently exist between North and South Korea.
However, Unites States President Donald Trump with his “America First” policy is fast becoming responsible for a new global order. This new global order involves power and influence moving away from the United States and parts of Europe and towards China, Russia, and India
