Trump signs space force plan: 'We have to be prepared'

Hailing 'next step', president accepts plans to create organization on a lesser scale than he had hoped

Donald Trump on Tuesday directed the Pentagon to develop plans to create a new space force within the air force, accepting less than the full-fledged department he'd wanted.

Before signing a document instructing the defense secretary to draft proposed legislation, Trump said space was the "future" and the "next step".
