Anthony Scaramucci isn't holding back on what he thinks about the idea of the United States invading Greenland. The prominent political figure took to X on Sunday to lay out exactly why such a move would be catastrophic.

His main concern? An invasion would be viewed as an illegal war of aggression against a NATO ally's territory. Greenland is an autonomous territory of Denmark, which means attacking it would essentially mean attacking a close U.S. partner.

But the damage wouldn't stop there. Scaramucci warned that such an action could shatter the core trust architecture of U.S. alliances. Think about it: if America invades the territory of one ally, why would any other ally trust U.S. commitments?

The financial implications worry him too. He pointed to a potential boomerang effect on U.S. financial conditions, though he didn't elaborate on the specific mechanisms. And perhaps most damning: he called the whole idea strategically unnecessary.

While the scenario is hypothetical, Scaramucci's comments highlight how delicate international relations remain and how quickly aggressive moves could unravel decades of diplomatic work.
