HR McMaster, a former national security adviser during Donald Trump's presidency, has expressed skepticism regarding Trump's claims that he could swiftly negotiate an end to the ongoing war in Ukraine if he were to be elected again. Speaking on CBS's Face the Nation, McMaster referred to Trump's assertions as a "real myth" and emphasized that they reflect a fundamental misunderstanding of the nature of war. "I don’t really buy it," McMaster stated, highlighting the misconception that a favorable political resolution can be achieved without first securing a favorable military outcome. His comments come as Trump, the Republican nominee, continues to assert that he has the ability to resolve the conflict in Ukraine.
