Senkaku Islands: Could the U.S. Military and Japan Really Land Troops?

Senkaku Islands: Could the U.S. Military and Japan Really Land Troops?

Let’s speculate about what a deployment to the uninhabited islets—which adjoin Japan’s Ryukyu Islands but constitute an archipelago distinct from the Ryukyus—might look like. Start with the extreme case. If troops alighted on the Senkakus, would they build a permanent base? Doubtful—though less doubtful than in the past.

 

Japanese and U.S. amphibious services, then, have put forward like-minded warfare concepts and started putting them into practical effect. They commenced practicing techniques for combined amphibious operations long before Keen Sword 21. In fact, a boat unit from the JSDF Amphibious Rapid Deployment Brigade embarked with the USS America expeditionary strike group for maneuvers in the Philippine Sea last February, before the madness that is coronavirus set in.

The upshot is this: the allies seem to have in mind not a standing presence on the Senkakus, let alone a permanent base, but the capability to land there in a hurry, establish potent defenses and defy a PLA that is not especially well versed in amphibian combat to evict them. There are pros and cons to such a come-and-go scheme. One hopes Tokyo and Washington have agreed on triggers that should set it in motion. Otherwise, they could flounder while negotiating in a moment of crisis—and unwittingly grant the PLA the time to purloin and consolidate its island redoubt.

 

Let’s invite the ghost of Helmuth von Moltke to U.S.-Japanese councils of war.
