It took the threat of nuclear war with North Korea to reportedly get The White House to put a hold on the policy re-instituting the ban on open transgender service in the military.

A White House source, reports the The Washington Blade on condition of anonymity, said “A Guidance Policy for Open Transgender Service Phase Out”— which had been certified by the White House Counsel’s Office after repeated advice that it would result in lawsuits—was expected to be sent to U.S. Secretary of Defense James Mattis sometime during the week starting Aug. 7.

However, according to a Pentagon source, after President Donald J. Trump and North Korean dictator Kim Jong Un 김정은 got into a fiery verbal sparring match on Aug. 8, the Defense Secretary sent a message to major U.S. commands letting them know that the threat by North Korea was his overriding priority and that other issues “were to be temporarily sidelined.”

Additionally, the Pentagon source says that Mattis intends to put a hold on all personnel matters, though disciplinary issues such discharges will continue. However, anything that affects military strength and readiness, specifically troop numbers, will be put on hold. Meanwhile, the Pentagon confirmed to the New York Times Aug. 9 that it has not yet received the trans guidance.

More pressing is possible nuclear war. On Aug. 5, the United Nations Security Council imposed tougher economic sanctions on North Korea after the isolated country tested two intercontinental ballistic missiles. China and Russia voted with the United States, something of a diplomatic coup, considering China’s connections to North Korea.

Trump and his advisers had been warned by President Obama and National Security Adviser Susan Rice that Kim Jong-un was developing a threatening nuclear program—a fact made more concerning when the Washington Post reported that North Korea has developed a miniaturized nuclear weapon that can fit on top of an ICBM, which is capable of reaching the United States. Los Angeles, considered a prime target, is 5,935 miles from North Korea.

“North Korea best not make any more threats to the United States,” warned Trump from his golf club in Bedminster, N.J.

They will be met with fire and fury like the world has never seen.

He has been very threatening — beyond a normal statement,” Trump said of Kim Jong-un. “As I said, they will be met with fire, fury and frankly power the likes of which this world has never seen before.”

North Korea threatened a preemptive strike creating “enveloping fire” against Guam, a sovereign U.S. territory that’s home to combined Navy and Air Force forces at Joint Region Marianas, with 6,000 service members, a port for nuclear submarines and other major military forces and more than 162,000 Americans. Last June, Guam held its first LGBT Pride parade with 150 people, including Guam Legislature Speaker Benjamin Cruz.

While Mattis did not specifically mention tabling the transgender service ban, it can be extrapolated that dealing with such a major policy change would be exceedingly disruptive during a time of crisis, especially when a military leader would want the ability to deploy all available troops.
