President Donald Trump’s new Greenland security agreement has drawn sharp reactions from investors Peter Schiff and Michael Burry.

Schiff argued on X that Trump had effectively abandoned his earlier push to acquire or annex the territory, settling for enhancements to the existing security structure after a "costly public pressure" campaign. He contended that the public threats to invade caused more reputational harm than the concessions gained.

Questions on Permanence

Schiff challenged the characterization of "permanent control" asserted by Trump and US Secretary of State Marco Rubio. He wrote that the control is conditional: "That control only lasts so long as the NATO alliance remains in place. When NATO ends, so does the new deal."

Responding to users who argued the agreement provides a permanent strategic lockout of Russia and China, Schiff pushed back, stating the deal is not permanent in isolation but tied to the broader alliance framework.

Missile Defense Value

Michael Burry highlighted the military significance of the island, resurfacing a January analysis. He pointed to two potential advantages for the US:

• Positioning missile defenses to intercept incoming Russian or Chinese ICBMs.
• Deploying offensive missile capabilities closer to those countries.

Burry noted that Greenland lies near the trajectories of missiles traveling between Russia and North America and near the region where ballistic missiles reach their highest altitude, or apogee.

Deal Terms Preserved

The agreement grants Washington permanent security control over the Arctic territory while expanding its military presence and barring rivals from accessing critical minerals. It does not transfer sovereignty to the US.

Denmark and Greenland confirmed the pact recognizes Danish sovereignty and Greenlanders’ right to self-determination. The territory remains part of the Kingdom of Denmark. Danish Prime Minister Mette Frederiksen said the agreement strengthens security in the Arctic and North Atlantic.

Key Projects

Greenland Mines closed its purchase of the Sarfartoq Nd-Pr Rare Earths Project on September 1. The $2.05 billion project could produce about one-third of the amount refined globally outside of China. Critical Metals Corp. announced a breakthrough at its Tanbreez heavy rare earth project, processing over 99% of eudialyte concentrate into ultra-high-purity products.

Next Steps

The agreement is expected to be formally signed during the UN General Assembly next week. It requires parliamentary procedures in Denmark and Greenland. The US already maintains a presence at Pituffik Space Base under a longstanding defense arrangement.

• Michael Burry highlights Greenland's missile defense role
• Sovereignty remains with Denmark and Greenland
• Adversaries barred from critical mineral investments

Sen. Elissa Slotkin argued on Saturday that an immigration system focused on legal, vetted entrants is necessary to support the US economy amid a rapidly aging population.

Slotkin posted on X that such a system would allow immigrants seeking a better life to contribute to the nation's economic future while reflecting American values.

Demographic and Economic Rationale

In a video accompanying her post, Slotkin highlighted the demographic shift as a primary driver for policy change. "If we want to grow as a state, we need to acknowledge we’re getting older," she said.

She asserted that immigrants are critical drivers of "innovation" and "entrepreneurial activity." Slotkin emphasized that the proposed system should enable legal, vetted individuals to "come work here and play."

Policy Context and Debate

The call for reform comes as the Trump administration proposes changes to the 2030 Census that could exclude undocumented immigrants and some non-permanent residents from congressional apportionment counts. The proposal also seeks to remove certain demographic questions, drawing criticism from New York Attorney General Letitia James.

Separately, the State Department is reportedly considering requiring parents to prove US citizenship or lawful status when applying for passports for their children, part of broader efforts to alter birthright citizenship rules.

Divergent Views on Enforcement

Sen. Rand Paul (R-Ky.) recently called for stronger enforcement and an end to taxpayer-funded benefits for noncitizens, citing impacts on border communities and emergency rooms.

Economists offer mixed views on the labor market impact. Moody’s chief economist Mark Zandi linked rising unemployment among US-born workers to weaker labor demand and immigration policies, warning that reduced immigration could contribute to stagflation alongside tariffs and supply-side shocks. Conversely, investor Bill Ackman has urged an overhaul to retain top talent through fast-track visas to spur business creation.

What the Numbers Show

While no specific financial figures were disclosed in Slotkin’s statement, the debate centers on the structural dependency of the US workforce on immigrant labor. The divergence between Zandi’s warning of stagflation from reduced immigration and Paul’s focus on enforcement highlights a split between macroeconomic stability concerns and fiscal/border security priorities.
