Two Weeks in Review: 26 January—6 February 2026

The last two weeks have taken us from headlines to bylines and beyond. Front-page legal questions on USA-Greenland and Russia-Ukraine continue to occupy commentators. While others draw our attention to the lesser thumbed back pages: from colonial-era agreements in contemporary arbitration, and the recognition of Somaliland, to the "stateless eight" suspended in legal limbo at the International Residual…
