A crucial security policy document outlining the future of the Philippines-United States alliance will be released in Washington when President Ferdinand Marcos Jr. visits the Pentagon for a meeting with American defense officials on Wednesday, a senior US embassy diplomat said.   Earlier announced in a White House factsheet following a meeting between US President Joe Biden and Marcos on Monday, the Bilateral Defense Guidelines are seen as an upgrade to the Philippines and America’s security ties as they seek to “institutionalize key bilateral priorities, mechanisms, and processes to deepen alliance cooperation and interoperability across land, sea, air, space, and cyberspace.”   “One thing that  out of this visit and is on track to be made public this Wednesday when President Marcos visits the Pentagon is the first ever Bilateral Defense Guidelines between the US and the Philippines,” said Brett Blackshaw, political counselor at the US Embassy, at a forum hosted by Stratbase-ADR Institute on Tuesday.
