Ukraine is a proxy for globalism and Russia is fighting to preserve its national security and identity. From Douglas MacGregor at theamericanconservative.com:
Washington’s proxy war in Ukraine is the globalist scheme to transcend the continuity of history, culture, and geography embodied in the nation-state.

During the 1999 Kosovo air campaign, President Bill Clinton told Americans, “That’s what this Kosovo thing is all about.… It’s globalism versus tribalism.”
In 1999 very few Americans paid attention to Clinton’s remarks. Kosovo was yet another conflict on someone else’s soil with little or no relevance to daily life in America. Frankly, Clinton’s use of the word “tribalism” probably confused many Americans. To most Americans, nationalism means devotion to the country, the U.S. citizen’s readiness in crisis or conflict to place the needs of the country above the citizen’s own. American nationalists aren’t tribal. They want to protect and defend the United States, its historic institutions and the rights embodied in its laws, not start wars.
The term “globalism” has since evolved to mean much more than free trade and comity between nations. Today, the Western nation-state and the nationalism it inspires are condemned by globalists as the sources of prejudice, exclusivism, and war. In retrospect, Clinton’s use of the term “globalism” is in continuity with the Biden administration’s proxy war against Russia.
