Trump’s halt of “war games” could set off diplomatic damage

WASHINGTON» President Donald Trump’s decision to suspend major U.S. military exercises in South Korea could weaken allied defenses, depending on the length and scope of the hiatus. But the potential for diplomatic damage seems even greater.

The United States, South Korea and Japan were making a public display of solidarity Thursday over the outcome of Trump’s summit with North Korea’s Kim Jong Un. But analysts and former officials with experience in U.S.-Asia policy were shaken by Trump’s failure to inform the Asian allies — or even the Pentagon — before mothballing the military maneuvers.

“Those exercises are critically important because they are deterrence,” said Chuck Hagel, a former defense secretary in the Obama administration. He welcomed Trump’s willingness to talk to Kim but worried that the president has underestimated the complications he has introduced for the Pentagon by suspending the military drills.

“You don’t just shut them on and off like a water faucet,” he said.

The exercises in question go well beyond routine training, which apparently is unaffected by Trump’s decision. Large-scale exercises are done to ensure that evolving tactics, procedures and plans can be carried out smoothly and that U.S. and South Korean forces are in sync. They also are a means of showing allied solidarity, which is part of the psychology of deterring enemy attack.

The U.S. has insisted the drills are defensive measures to demonstrate U.S. and South Korean preparedness to respond promptly to any aggression by the North. But when Trump announced his decision to halt them, he characterized them as “provocative” and as “war games.”

“Those are literally the North Korean and Chinese talking points,” said Christine Wormuth, the Pentagon’s top policy official from 2014 to 2016. She noted that the North and China have long complained that the military exercises, including those involving U.S. strategic bombers, are a rehearsal for invasion.

Michael Green, who was Asia director on the National Security Council staff during the George W. Bush administration, said the likely damage from suspending drills is multiplied by Trump’s failure to inform South Korean and Japanese officials in advance and his focus on cost-savings from the suspension. This was compounded, in Green’s view, by Trump’s dubious assertion on Twitter that North Korea no longer poses a nuclear threat.

“The No. 1 problem with this, geopolitically, is that it suggests to our allies that we are just incompetent, that we don’t recognize the threat,” Green said.
