Empire Crumbling

The great imperial retreat continues. President Donald Trump’s decision to substantially reduce joint military exercises with South Korea may be presented as a dispute over costs, burden-sharing and relations with North Korea, but its symbolism reaches far beyond the Korean Peninsula.
The Gulf has already offered a warning. States that had built their security around American guarantees have watched Washington struggle to shield the region from the consequences of the Iran conflict and the disruption surrounding the Strait of Hormuz. South Korea, Japan and Taiwan will inevitably study those lessons. Security commitments are only as strong as the confidence others place in them.
Trump has not abandoned South Korea, nor has the US withdrawn its forces or formally weakened its treaty obligations. Yet strategic influence is rarely lost in one dramatic act. It erodes through accumulated signals of hesitation, conditionality and fatigue.
Reducing a major exercise at the last moment, particularly after openly criticising Seoul for refusing to participate in action against Iran, sends precisely such a signal. The additional emphasis on Trump’s relationship with Kim Jong Un only deepens uncertainty over where allies rank when American priorities shift.
More troubling for Washington is the wider regional perception. Any move interpreted as accommodation towards Beijing, directly or indirectly, will rankle allies already anxious about China’s expanding military and economic power. Beijing does not need America to leave Asia entirely; it merely needs regional capitals to doubt that Washington will always stay.
The United States remains the dominant military power across much of the Pacific, and its alliances remain formidable. But empires and spheres of influence rarely disappear overnight. They retreat inch by inch as commitments become negotiable and allies begin preparing for a world in which they must increasingly fend for themselves.
Across the South China Sea and beyond, that process appears to be gathering pace.
