In a rare convergence of political will, President Trump signed into law a sweeping bipartisan sanctions package designed to strangle the economic lifelines sustaining Russia's war in Ukraine. The legislation — a final legacy of the late Senator Lindsey Graham — targets the officials, banks, and shadow tanker fleets that keep Moscow's war machine funded. It is a moment that asks an enduring question: whether economic pressure, applied with enough force and consensus, can bend the arc of a conflict that diplomacy alone has failed to resolve.
