The Washington Post is not happy that the US is not participating in talks with North Korea and the ROK and has thus declared that the President is now irrelevant:

But whatever happens, it does look like U.S. policy on North Korea is rubbing up against the limitations of Trump’s unilateralist view of the world — what Evan Osnos of the New Yorker recently dubbed “retreating from the front.” When Seoul-Pyongyang talks go ahead next week, Trump will be in an unusual position — watching from afar, having capitulated on one key North Korean demand.

The Trump administration had hoped to further isolate North Korea on the world stage. Thanks to Trump’s brash tactics, though, it may be the United States that ends up on the outside.  [Washington Post]

First of all, President Trump did not capitulate on the delay of the Key Resolve exercise.  North Korea wants joint exercises cancelled and so does the Chinese.  The US did not cancel the exercise, they delayed the exercise at the request of the ROK who did not want it to overlap with the Winter Olympics especially if the North Koreans decide to attend.  The exercise is still going to happen just like it does every year and thus there has been no capitulation.

As far as “retreating from the front” and claims of unilateralism, these critics of the President must be living in an alternate reality.  The Trump administration has arguably pursued more multilateral measures than past Presidents.  The Trump administration has aggressively pursued and implemented United Nations sanctions on North Korea.  The Treasury Department has aggressively worked with international partners to target the Kim regimes finances through the global banking system.  They have also worked with other countries to kick out North Korean diplomats often responsible for bringing in foreign currency to the regime.  Unprecedented pressure has also been put on China by the US to faithfully implement sanctions on North Korea.  US intelligence has worked with the ROK to seize ships smuggling oil into North Korea.

Just because the US is not sitting at the table with the ROKs and the North Koreans to discuss a delegation attending the Olympics does not mean US policy is unilateral and the Trump administration has made themselves irrelevant.
