The record since

  • 18 Oct 26 No. 110 · revised to 80%
    Mexico City publicly faulted Chihuahua officials for not coordinating with federal authorities on U.S. agents, and Sheinbaum said the relationship is federal, not state.

What would overturn it

A public statement from Sheinbaum's administration or Governor Campos reopening the dispute over U.S. agents' role or presence in Chihuahua, versus the joint-security arrangement holding without further public friction.

The verdict

Open  Resolves by 20 Mar 27 — graded at the weekly Reckoning against the criteria above, and recorded here.

As logged at issue

Roughly even odds Chihuahua's state government and Mexico's federal government publicly clash again over the role of U.S. security personnel within six months, since today's reconciliation addressed the immediate dispute but not the underlying jurisdictional friction.
