Trump and Hegseth lost the Iran War, because they don't understand war properly. They think the expensiveness of a weapon's system is what matters. It's like the old Spinal Tap joke ("But this one goes to eleven."), where you can't even see the stupidity of the metrics that you're using. With Hegseth's hard-on for "lethality" he completely missed that wars are inherently political acts and leading a democracy to war requires public suasion first and foremost. Sometimes (Pearl Harbor, Fort Sumter, 9/11) that suasion is handled by your enemy. Trump/Hegseth never made a case for the war, they just did it, trusting that the disparity in military budgets would carry the day. It has been the political will and the ability to leverage cheap drones that has led to an Iranian victory (and it leading to a Ukrainian one, as well).
Of course, the Iran War isn't Trump's only ongoing war. His trade war with Canada is now accelerating. Like the previous example, Trump's fundamental stupidity means that he doesn't understand the basic dynamics of the situation. The US and Canadian economies are mixed together; trade wars make zero sense. Like with Iran, it's a question of political will. Canada is united, the US is not. What's more this will have its biggest impact in states close to Canada. Are their important elections in Maine, Michigan, Alaska and Wisconsin, I wonder? Are farmers' votes important in Iowa, Nebraska and Kansas?
I know I've beaten this dead horse to a bloody pulp, but Trump doesn't understand the process of creating a policy, because he spent his entire adult life running a company of about 10 people, bullying other people and then going bankrupt. He never had to do real horse trading or compromising; in fact, he finds those things contemptibly weak.
When Trump looks at the smoldering mess he's making, he blames it on Biden. This isn't just his malignant narcissism. This is his entire way of doing business over the past 50 years. Nothing his fault; attack, attack, attack; deflect, deflect, deflect; never admit weakness. Character really is destiny. Ignorance really isn't bliss.
If Democrats and independents wind up sweeping through elections in the Great Plains and along the Canadian border, it will be because Donald Trump has dragged us into wars that we did not have to fight, with goals that were unrealistic in the most optimistic projections and have been waged with a fecklessness that would shame a toddler.
