This event scores 0 on constitutional damage as it involves a foreign leader's warning about potential future tariffs with no mechanism affecting U.S. constitutional structures. No drivers are triggered: no election interference, no rule of law impact, no separation of powers issues, no civil rights concerns, no institutional capture, no corruption, no violence. The B-score of 7.46 reflects moderate media attention (trade war rhetoric is familiar) with some outrage potential around consumer prices, but lacks viral characteristics or significant strategic manipulation. The event is fundamentally speculative (Trump 'decides to impose' - conditional future tense), represents routine diplomatic posturing between trading partners, and involves no actual policy action or constitutional mechanism. This is standard international trade rhetoric that generates headlines but represents no substantive threat to constitutional order.
