That means it is entirely possible that a slew of miscalculations are being made today. One of the most widespread misconceptions about the U.S. political system is that a president who is weak at home is by default weak abroad. This is a belief primarily promulgated by Americans themselves. After all, if one cannot get behind one’s leader, what business does that leader have engaging in global affairs?
But in reality, a president who is weak at home often wields remarkable power abroad. The U.S. Constitution forces the American president to share domestic power with Congress, so a split government leads to domestic policy gridlock. However, the Constitution also expressly reserves all foreign policy — particularly military policy — for the presidency. In fact, a weak president often has no options before him except foreign policy.
This is something that the rest of the world repeatedly has failed to grasp. Domestically weakened American presidents have often done more than engage in foreign policy: They have overturned entire international orders. Former U.S. President George W. Bush defied expectations after his 2006 midterm electoral defeat and launched the surge in Iraq, utterly changing the calculus of that war. Clinton launched the Kosovo War, which undid what remained of the Cold War security architecture. Most famously, John Kennedy, whom the Soviets had written off as a weak and naive dilettante who had surrounded himself with incompetent advisers (sound familiar?), gave the Russians their biggest Cold War diplomatic defeat in the Cuban Missile Crisis.
The United States might be distracted and its president domestically weakened, and undoubtedly most of the world will assume that they know what this means. But history tells a very different story, and this president — like his predecessors — is not done just yet.
