Why would President Trump want to allow Russia to continue its campaign against Ukraine?

According to General Sir Richard Shirreff, Trump's approach stems from a fundamental lack of understanding of Russia's imperial ambitions. The former NATO Commander suggests Trump fails to recognize the threat Russia poses not only to Ukraine but potentially to NATO members like the Baltic states. This misunderstanding could lead to dangerous outcomes where Russia brings NATO into direct confrontation by expanding its aggression beyond Ukraine. Shirreff implies that Trump's permissive stance toward Putin might inadvertently encourage Russian expansionism, threatening European security architecture and NATO's collective defense principle.
