How the US and UK Strengthened Their Grip

Recent news articles highlight several initiatives where the United States and the United Kingdom are strengthening their historical partnership:

1. Technology Partnership Deal:

On September 18, 2025, the U.S. and UK signed a landmark technology partnership agreement during President Donald Trump’s state visit to Chequers, focusing on cooperation in advanced industries like artificial intelligence, quantum computing, and nuclear energy. The deal, described as the largest investment package in British history, is expected to generate billions in transatlantic trade, create up to 15,000 jobs, and foster innovation. Notable projects include U.S.-based X-Energy and UK-based Centrica collaborating to build nuclear reactors across the UK, reinforcing economic and strategic ties.

2. Cryptocurrency Regulation Cooperation:

On September 17-18, 2025, reports emerged of the U.S. and UK planning closer collaboration on cryptocurrency oversight to boost innovation and financial stability. Discussions between UK Chancellor Rachel Reeves and US Treasury Secretary Scott Bessent aim to align digital asset regulations, positioning the UK as a hub for digital asset innovation post-Brexit and ensuring competitiveness for dollar-denominated stablecoins.

3. Military and Defense Collaboration:

On June 6, 2025, U.S. Representative Mark Green introduced a bill on the 81st anniversary of D-Day to expand military technology sharing between the U.S. and UK, aiming to amend the International Traffic in Arms Regulations (ITAR) to grant the UK exemptions similar to Canada. This move seeks to strengthen the military partnership, building on historical cooperation.

4. State Visit and Symbolic Reinforcement:

During Trump’s state visit to the UK on September 18, 2025, both Trump and UK Prime Minister Keir Starmer emphasized the “special relationship,” with Trump calling the U.S. and UK the greatest contributors to humanity and Starmer declaring a “new era” in ties. The visit, including meetings with King Charles III, underscored cultural, economic, and diplomatic bonds.

These developments build on earlier efforts, such as a May 2025 trade deal celebrated as a milestone for economic prosperity and a November 2024 amendment to the 1958 Mutual Defense Agreement, enhancing atomic energy cooperation for defense purposes. The partnership is framed as a continuation of a historic alliance, though some sources note challenges like global divisions and differing strategic priorities.
