Republican candidate Vivek Ramaswamy criticized Nikki Haley, Joe Biden, and their lack of foreign policy knowledge. Ramaswamy questioned their ability to name three provinces in Eastern Ukraine that they would deploy US troops to. He highlighted the importance of leaders with a solid grasp of foreign affairs. Ramaswamy also criticized Haley for her lack of historical acumen, specifically her failure to mention slavery as the primary cause of the Civil War. These remarks come at a time when foreign policy decisions are under scrutiny, including president Biden's authorization of the deployment of 3,000 US troops to Poland, Germany, and Romania.
