US national security: Trump set to make key policy speech

Donald Trump has hoped to readjust US strategic priorities, but thus far, his administration has struggled to match his rhetoric, largely aping or following the policies and priorities of his predecessor, Barack Obama.

US President Donald Trump will unveil his national security strategy later on Monday.

He’s expected to take aim at the US’ geopolitical rivals and identify key global challenges.
