issue: #52 [17/50][北米・中南米] メキシコの国際政治上の論点を調査する
request: Research Mexico as a country profile that helps readers follow news through the lenses of regional history, political institutions, security, economics, and civic life.
scope: presidential power, security institutions, courts, local politics, U.S. trade, migration, borders, drug policy, nearshoring, autos and manufacturing, energy policy, cartel violence, disappearances, press freedom, and civic life.
deliverable: a Japanese report at articles/report/mexico-geopolitical-profile/ja/index.mdx, a matching English report, mix-alignment.json, public source notes, and a public research log.

The current political system needed to be read through federal presidentialism, a Morena-leaning legislature, and the tension created by judicial reform.
The U.S. relationship had to be treated as a single package of trade, border management, migration, security, and the USMCA review.
Security had to be split into homicides, disappearances, extortion, and press freedom instead of treating violence as one undifferentiated trend.
The economy had to be read through nearshoring together with rule of law, electricity, and permitting constraints.

The federal constitution, INE election results, the judicial reform decree, SRE statements on U.S. coordination, USTR material on USMCA review, Banxico material on nearshoring, SSPC security updates, CNB/RNPDNO disappearance data, SENER energy plans, and MOFA/JETRO material on Japan were the core sources.
RSF, HRW, Amnesty, the INE history page, and the government’s 200-year republic material were supplementary context.

Reuters and AP stories were useful context but were not used as core evidence because the report is anchored in official and primary sources.
Commentary that tried to close the book on the 2026 USMCA process was excluded because the review is still in motion.
Disappearances, press freedom, and local violence were kept as separate questions rather than folded into a single security trend.

The article is organized around history, institutions, U.S. relations, security, the economy, energy, and Japan-facing implications.
The main actor table and external-relations table make the power structure visible for news reading.
The timeline and diagram keep the institutional shift from the post-revolutionary state to the current USMCA review readable at a glance.

It is still unclear how far judicial reform will reduce court independence in practice.
The USMCA review could land on rules of origin, labor enforcement, energy policy, or customs, but the final shape is still unsettled.
Homicide averages may improve without producing the same change in disappearances or extortion at the state level.
Nearshoring is strong, but power, permitting, and transmission constraints may still cap the upside.
