Another stop in the non-intervention tour. In 1968, Wenceslas Square in Prague became a focal point of resistance against the Soviet-led invasion of Czechoslovakia. After the Prague Spring was suppressed, Brezhnev proclaimed his doctrine of limited sovereignty.

Another stop on the #nonintervention tour. The Nyon Agreement was signed on 14 Sept 1937. Nyon was chosen to avoid association with the League of Nations, which was viewed unfavorably by Italy. The agreement addressed attacks on international shipping during the Spanish Civil War

This looks a lot like economic coercion to me, prohibited by the principle of non-intervention (as codified in the UN Friendly Relations Declarations) and by Art. 3 of the 1994 Budapest Memorandum www.reuters.com/business/us-...
Exclusive: US could cut Ukraine's access to Starlink internet services over minerals, say sources
Ukraine's access to SpaceX-owned Starlink was brought up in talks between U.S. and Ukrainian officials after Ukrainian President Zelenskiy turned down an initial proposal from U.S. Treasury Secretary Bessent.

“The growing normalization of violations of international humanitarian law poses an existential threat to the Geneva Conventions and international law more broadly. This alarming trend requires urgent collective action.”
Communities uprooted. Families torn apart.
Vital infrastructure destroyed.
As conflicts escalate worldwide – from Gaza to Sudan, Myanmar to Ukraine – civilians are bearing the brunt.
Emerging threats – autonomous weapons, cyber warfare – are compounding the challenges.

The long delay to the ICC arrest warrant process is due to significant pressure on the court by Israel and the United States.
