For clarification, your argument on the Homeland defence definition isn't for me. Everything I wrote was derived or deducted from the following.
1. In June 2025, Greenland was moved from the EUCOM to the NORTHCOM AOR.
Pentagon Places Greenland Under US Northern Command
2. The preamble to NORTHCOM's
Mission Statement:
U.S. Northern Command (USNORTHCOM) was established Oct. 1, 2002 to provide command and control of Department of War homeland defense efforts and to coordinate defense support of civil authorities. We defend America's homeland — protecting our people, national power, and freedom of action. Integrated and aligned with North American Aerospace Defense Command (NORAD), a bi-national command responsible for aerospace warning, aerospace control, and maritime warning, we share a common goal of defending North America.
3. The Biden Administration published the most up-to-date US defence strategy document in June 2024. The Introduction to the
2024 Department of Defense Arctic Strategy by then SECDEF Lloyd Austin states:
The United States is an Arctic nation, and the region is critical to the defense of our homeland, the protection of U.S. national sovereignty, and our defense treaty commitments. I am issuing this 2024 Arctic Strategy to guide the U.S. Department of Defense (DoD) in a concerted approach to preserve the Arctic as a stable region in which the U.S. homeland remains secure and vital national interests are safeguarded.
The US DoD, not me, made the linking of Greenland to US Homeland Defence (whether you agree or not).
None of the above recommends or endorses Trump’s current policy of seeking direct sovereignty over Greenland.
Both the CBC and Small Wars Journals have written good pieces analyzing recent developments. Both touch upon Greenland, US Homeland Security, US underinvestment, lack of NATO action, Chinese involvement, and natural resources.
The Strategic Importance of Greenland
U.S., NATO have long history of not being serious about Greenland. That's about to change
Lastly, I have already posted this, but good background on the assessed future threat environment, the
