The Trump administration has redefined the core principles of U.S. foreign policy, moving away from traditional geopolitical maneuvering toward a transactional model that prioritizes economic trade-offs. Where previous administrations framed diplomacy as a tool to manage political and security alliances, the Trump White House has embraced a results-driven, geo-economic strategy. This shift is exemplified by the ongoing U.S.-Russia negotiations over Ukraine, currently taking place in Riyadh without European or Ukrainian participation.
