The True Meaning of Power

Foreign Affairs | David Sacks

Hans Morgenthau’s classical realism established that international relations remain an unyielding struggle for power, yet his framework simultaneously demanded moral self-restraint to prevent self-destructive overreach. Today, the second Trump administration pursues aggressive unilateral force across Iran, Venezuela, and the Caribbean while dismissing international norms and allied consultations. This expansive posture highlights a fundamental strategic trade-off between unbridled short-term power projection and the long-term institutional legitimacy that sustains national influence.

Unchecked power untethered from normative constraints leads to strategic isolation, as partner states cease deferring to American leadership when moral limits are abandoned. Historical realism demonstrates that countervailing power and diplomatic norms alone prevent catastrophe in intense great-power competition. National power relies on restraint. Washington risks eroding its own domestic democratic foundations and alliance networks through unrestrained foreign entanglements. Ultimately, calibrating military strength against ethical boundaries remains essential to avoiding miscalculations in an era of heightened global friction.

Comment

The friction between immediate coercion and long-term coalition access exposes a fundamental operational trade-off in U.S. defense policy. As detailed in Hans Morgenthau’s 1948 text *Politics Among Nations*, material power loses its strategic utility when uncoupled from international norms. Unilateral strike operations around Iran and Venezuela generate brief tactical deterrence. However, this aggressive approach degrades the strategic consensus underpinning broader frameworks like the Monroe Doctrine.

A direct second-order consequence of this trade-off is the erosion of host-nation basing privileges across U.S. European Command. Partner nations facing domestic political pushback routinely restrict intelligence sharing and staging access when American military actions bypass normative constraints. Consequently, U.S. European Command risks encountering stringent diplomatic caveats at key operational hubs such as Ramstein Air Base.

Strategic Question for Discussion

Which factor imposes a greater operational constraint on U.S. European Command during crises—the loss of norm-based legitimacy among allies or the physical restriction of staging facilities like Ramstein Air Base?

The available evidence points toward physical facility restrictions as the more immediate operational bottleneck, as host-nation caveats at Ramstein Air Base directly impair real-time deployment timelines. However, the broader erosion of norm-based legitimacy presents a far more severe long-term vulnerability for U.S. European Command by permanently weakening coalition integration. My assessment is that while diplomatic friction can be managed in short-duration operations, structural access restrictions compound rapidly during sustained multi-theater contingencies.
