Trade alliances, security partnerships, and multilateral institutions once treated as permanent structures are now being weaponized, abandoned, and reconstituted based on immediate transactional gains. Nations are openly prioritizing economic or security advantage over collective commitments, treating allies as expendable when alignment diverges. The pattern spans trade (tariffs, supply chain reconfigurations), defense (equipment delays, strategic ambiguity), and diplomatic engagement (Iran negotiations, settler violence in occupied territories).
