Very often we think that Donald Trump is "crazy" and that his actions are unpredictable and disconcerting, or even delirious, chaotic and irrational. But these labels do not help to see a fairly coherent pattern behind increasingly aggressive interventions: weakening rivals indirectly and ensuring relative gains for the United States. We are facing proxy geopoliticsproxy.This idea is a reinterpretation of the concept of "proxy wars" that became popular during the Cold War, when major powers provided military, economic, or political support to allied governments in distant conflicts (in Korea or Vietnam, for example). This way they harmed the enemy while avoiding a direct confrontation between powers with nuclear weapons.We could say that proxy geopolitics is the compass of Trump's foreign policy, both in contexts of peace and war. Through interventions in third countries, it essentially seeks to weaken rival powers and gain an advantage in economic, energy, or military matters. This is how explicit the US national security strategy, published last November, is: "We must prevent other actors from achieving global dominance [...]. This implies working with partners to counter ambitions that endanger our interests." It's not about winning, but about defeating others.The eight peace agreements that Trump boasts of having achieved have not stopped violence nor brought stability. But this was not the objective. Many of these agreements seek to limit the influence of other major powers. For example, in the agreement between the Democratic Republic of the Congo and Rwanda, Trump secures the exploitation of mineral reserves in a region that was mostly dominated by Chinese companies; while in the agreement between Armenia and Azerbaijan, US contractors will develop railway lines, gas, and oil for a century, limiting the influence of Russia and China in the Caucasus.
