Guatemala seeks US-assisted active military operations against cartels following reported joint-strike agreement

Analysis
A confirmed joint kinetic operation inside Guatemala within the next 90 days is unlikely. Arévalo publicly named the legislature as the constitutional authority for any foreign military presence, a constraint he invoked the same day the NYT report surfaced and that now sets the political ceiling on what he can authorize without domestic cost. The Saenz letter's "Guatemala-led operations with US assistance" framing preserves sovereignty optics while still requesting kinetic support, meaning the cooperation request survives the denial even as the joint-strike characterization does not. That distinction limits SOUTHCOM to an advisory and enabling role unless Guatemala's congress acts, which Arévalo has given no indication of requesting. Moderate confidence reflects documentary grounding in the Saenz letter and Arévalo's on-record constitutional citation, though internal deliberations between the two governments are not visible to open-source collection.
