I know Reagan could have expressed the same ideas to/about Zelensky without handing the left a photo op.
Trump does not "lack" nuanced diplomacy - he abhors it. His message to Zelensky is that Ukraine will do what USA and Russia and China has decided they will do, or the war will go on and Ukraine will die slowly. It's about commerce - not geopolitics. Trump doesn't give a damn what some trans-teaching Euro state feels about NATO. And he think the US wins any tariff war, so he uses it.
