Institute for Global Affairs and History (IGAH)

Research on international affairs and history

A research project of GlobeZenith OÜ. It examines international affairs and modern Japanese history against published primary sources and data, and turns the results into articles.

Quotes and figures are checked against the original sources by code. Anything that fails is not published
A separate AI, not the one that wrote the piece, reviews it as a devil's advocate
