Why allies cannot simply fill every US escort gap

Will shrinking fleets force allied navies to combine task groups more often to cover each other's gaps?

To an extent, but most allies have lost spare escort capacity and now need their remaining ships for their own carriers and national missions.

Joint task groups depend on partners both wanting to contribute and having ships available. The Royal Navy comparison recalls the 1998 reduction from 35 escorts to 32 and contrasts that scale with the much smaller fleet described in the video. Japan's carrier conversions create additional protection duties for its own escorts. The wider argument links reliance on US maritime policing with reduced allied capacity, and interprets dependence as a possible short-term diplomatic advantage with later operational costs. The British Empire is offered as a historical analogy for a leading power performing expensive maritime policing that other states benefit from. These interpretations support the warning that allied ships cannot simply be counted as spare capacity before national commitments are considered.
