Objectives:
Analysis of geopolitical changes in the world resulting from Russia's aggression in Ukraine in 2022.

Methods:
The research methods include the analysis of reports and documentation and the current political and military situation.

Results:
The article answers four research questions: 1) To what extent does Ukraine represent a pivotal point in a limited Cold War with Russia countering the expansion of democracy? 2) What is the future of Ukraine and what issues remained to be resolved? 3) What are the differences between the Cold War of 1947-91 and today's limited Cold War? 4) Why did the West not want to believe that Russia would attack Ukraine? Three reasons are articulated: the West was blinded by the vision of "pursuing peace through trade" (especially in the field of energy).

Conclusions:
Ukraine's valiant struggle to save its democracy from Vladimir Putin's brutal invasion is the pivotal point of our time. As countries and companies seek to return to or maintain relations with Russia despite the brutal war that has disrupted the world order, it remains to be seen how long democratic nations will be able to maintain their unity. . On one side are the democratic nations of the West, the Pacific and NATO, and on the other are autocratic Russia, China and their allies. This is a renewed but limited Cold War that will dominate nations for decades to come.
