The collapse of weekend peace talks is more than a diplomatic failure — it’s the moment the Iran war begins to migrate from the foreign policy pages into domestic politics.And that’s where the real danger lies for President Trump and the Republican Party, which has largely marched in lockstep behind him.A few thoughts:Most foreign policy experts already view the Iran war as a serious strategic blunder. But that alone won’t move many voters. Foreign policy rarely does.Elections tend to turn on kitchen-table concerns. If the economy weakens or prices rise, the party in power pays the price.That’s why oil matters. Prices have already climbed well above where they started the year and are likely to remain elevated — if not surge further — depending on how long the Strait of Hormuz stays disrupted.A prolonged closure doesn’t just mean expensive gas. It risks supply shocks across the global economy, creating real shortages of critical goods alongside rising costs.At that point, the policy options narrow dramatically. Reopening the strait could require direct U.S. military intervention, including the possibility of ground forces.And that’s when the war stops feeling abstract for American voters. The moment American troops are drawn into a deeply unpopular conflict is the moment the political consequences crystallize — and the Republican Party’s chances of holding back a blue wave could collapse just as quickly as the negotiations did.What do you think?
