US leaves Subic Bay and Clark (1991–1992)
The Philippine Senate rejected a new lease in 1991, ending nearly a century of US basing. After the Mount Pinatubo eruption damaged Clark Air Base, the US handed back Subic Bay Naval Base in 1992, its largest overseas naval facility at the time.
The US lost its main forward base in Southeast Asia and relocated forces to Guam and Japan.
US power in the region thinned for years, until Manila invited a limited American return decades later under a rotational access deal.
A host country forcing a great power off a prized base shows how quickly basing rights can vanish when the political ground shifts.
