Donald Trump acted like he was anti-war, too. "Claiming (without evidence) that he had opposed the invasion of Iraq, Trump lambasted the bipartisan foreign policy establishment for its decades of disastrous militarism. For a war-weary nation desperate for change, this was evidence enough that Trump would be different. The “anti-war” label stuck, and it would be repeated over and over, up to the very final days of his presidency." https://responsiblestatecraft.org/2021/01/20/trump-the-anti-war-president-was-always-a-myth/
