Since 2014-2-27 Russia has occupied the Crimean peninsula. This invasion had started with an undercover mission of unmarked soldiers to take full control of Crimea about 3 weeks later. Russia did not officially declare a war, although the intentions were identical to a land grabbing war. The western world did not react much to this violation of international law. Apparently, this contributed to the next cynical “special operation” by the Russian army to fully invade Ukraine on 2022-2-24 in a failed “Blitzkrieg”, a rapid invasion, which attempted and failed to annex the whole of Ukraine. According to Lissner & Warden (2026) the Russian invasion of Ukraine bears 4 lessons for future conflicts: (1) the risk of using nuclear weapons is real, (2) in addition to nuclear options, prolonged and very destructive conventional wars remain an option, (3) escalation thresholds emerge and evolve over the duration of the conflict, (4) allies and partners in war keep adjusting their risk tolerance as well as escalation options. The authors argue from a US perspective and add a practical comment: “The USA cannot go this alone, but should coordinate closely with allies and partners in time before another conflict arises. Multilateralism seems a valid option and even more so as we move into a multipolar power play on the global scale propelled by AI.
