WASHINGTON (AP) — President Donald Trump views tariffs, and the threat of them, as a formidable tool to influence foreign nations. His unprecedented approach integrates tariffs deeply into both his economic strategy and foreign policy in his second term.


Trump has deployed import tariffs as a negotiating tactic, seeking ceasefires from warring nations and pressuring countries to curb drug trafficking across their borders. He has also used tariffs as a means of political leverage against countries like Brazil and in recent spats with Canada over advertising campaigns.


This week, the Supreme Court is set to hear arguments on whether Trump overstepped federal laws through his extensive use of tariffs. A ruling unfavorable to Trump could restrict or nullify this pivotal aspect of his foreign policy strategy.


The president has expressed increasing anxiety about this critical decision, labeling it potentially disastrous for the United States if lower court rulings that limit his emergency tariff powers are upheld.


The Justice Department defends Trump’s tariff actions as a legitimate exercise of presidential power over foreign relations, arguing that his tariff impositions are within his rights during national emergencies. However, a recent trend of lower courts has indicated that Congress, not the president, possesses the constitutional authority to impose tariffs.


Unlike previous administrations that generally wielded financial sanctions as instruments of foreign diplomacy, Trump has taken a blunt approach by using tariffs extensively, which some analysts argue complicates international relationships.


Modern presidents have typically seen tariffs as nuanced adjustments rather than outright threats. Trump’s administration has made waves internationally, leading some allies to gravitate towards protectionist policies or seek closer ties with less traditional partners, such as China. The economic ramifications are significant, with many businesses adjusting prices as they navigate the uncertain tariff landscape.


According to experts, taking tariffs as a primary tool for negotiating broader foreign relations is unprecedented, suggesting that if the Supreme Court restricts Trump's tariffs, it may influence future dealings and agreements.


Ultimately, the impending Supreme Court ruling holds potential consequences not only for Trump’s political capital but also for international relations and the economics of global trade.
