In this Briefing, Jon Decker breaks down President Donald Trump’s headline-making remarks at the World Economic Forum in Davos, where he once again emphasized the strategic importance of Greenland and why the United States should seek greater control over the Arctic region—despite resistance from Denmark. Decker explains how Greenland fits into America’s broader national security strategy and its role within NATO.

Decker also explores the potential impact of new U.S. tariffs on European nations, examining how trade pressure could reshape transatlantic relations and global markets. Finally, Decker unpacks a major Supreme Court of the United States case involving the firing of Federal Reserve Governor Lisa Cook, highlighting the growing legal and constitutional tensions between the executive branch and so-called independent agencies like the Federal Reserve.
