Comment:  Core 5 is emerging in the news as the next view working with the National Security Strategy.  This affects global power shifts and alliances. The C5 post contains verified links to articles explaining C5.

The UK and the European continent are missing from Core 5.  Core 5 deals with individual countries having a population of 100 million.

Executive Overview

A new strategic concept has begun circulating in global markets and business circles: a “Core Five (C5)” configuration involving the US, India, China, Japan, and Russia.

This idea is reportedly being considered and shaped by US President Donald Trump as a potential future framework for stabilizing global economic conditions, managing great-power rivalries, and creating predictable foundations for business and technology ecosystems.

Whether C5 becomes a formal alliance or remains an informal diplomatic architecture, its business implications may be profound.
