D. Trump has recently announced the signing of a global 10% tariff on all countries, which he stated will take effect almost immediately. This decision comes shortly after Trump faced a significant setback when the Supreme Court struck down large, targeted tariffs he had implemented last April, affecting specific nations. In his announcement, Trump expressed his honor in signing this tariff in the Oval Office, emphasizing his belief that it would complement existing tariffs already in place.

Prior to this announcement, Trump had signaled his intention to impose such a tariff, indicating that it would be enacted under Section 122 of the Trade Act of 1974. This section grants the president authority to introduce temporary trade measures to address balance of payments issues. Trump's latest move seems to be a response to the previous ruling from the Supreme Court, which posed a challenge to his more targeted tariff policies aimed at specific countries.

The implications of this global tariff are likely to be significant, potentially affecting international trade relations and economic dynamics. While Trump argues that this measure is necessary for economic stability, critics may view it as a controversial approach that could escalate trade tensions further. The timing of this announcement, following a judicial defeat, also raises questions about the motivations behind such a unilateral decision in the realm of international trade.
