After nearly six months in office, President Trump has not yet issued a classified presidential directive on national security.
On June 16, Trump issued an unclassified National Security Presidential Memorandum (NSPM) on US policy towards Cuba, reversing or limiting some of the steps towards normalization of relations with that country that were undertaken by the Obama Administration.
The version of the Memorandum that was published on the White House website was unnumbered, but a White House official said last week that it is formally designated as NSPM-5.
Since the first four Trump NSPMs are also unclassified public documents, this means that at least as of June 16 there were still no classified or unreleased presidential directives on national security.
That is unexpected, and it is a departure from past practice in previous Administrations.
The explanation for the lack of classified NSPMs is unclear.
It is possible that President Trump is using some other instrument for issuing policy directives on classified national security matters (though that would be at odds with the definition and purpose of NSPMs). Alternatively, he may have delegated certain aspects of national security decision making elsewhere, as with the authorization for the Secretary of Defense to determine troop levels in Afghanistan.
Or it could be that there just are no other Trump national security directives because there is no other Trump national security policy to speak of. The Administration may still be so understaffed that it is incapable of launching significant new policy initiatives.
The June 16 NSPM-5 directed the Secretary of State to publish it in the Federal Register. But three weeks later, even that simple task has still not been carried out.
