What would overturn it

A publicly confirmed joint interdiction operation naming Peruvian forces before June 11, 2027 is the signal we're wrong; continued coalition-level statements, intelligence-sharing announcements, or exercises with no named joint operation by then is the signal we're right.

The verdict

Open  Resolves by 11 Jun 27 — graded at the weekly Reckoning against the criteria above, and recorded here.

As logged at issue

Peru/Shield of the Americas: we think it's likely -- coalition membership is a policy commitment, and this brief's own record shows a policy or diplomatic announcement is repeatedly mistaken for the operational fact it precedes rather than proves. A named joint operation involving Peruvian forces before the deadline is the signal we're wrong.
