• The US has introduced a new strategic map for Homeland defense called Greater North America (GNA).
• GNA encompasses every sovereign nation and territory north of the equator.
• The strategy aims to defend the Homeland, protect critical infrastructure, and enhance warfighting readiness.
• The Department of War is operationalizing GNA through burden-sharing and partnerships.

The introduction of GNA may signal a shift in US defense priorities towards a more regional approach, which could enhance collective security and burden-sharing among partner nations. This strategy may also indicate a growing concern about non-Hemispheric state actors' aggressive moves in the region, which could lead to increased investments in defense infrastructure and supply chain resiliency.
