Trump says 'Space Force' to dominate foes, cites China

"Our competitors have begun weaponizing space," Trump warned troops at Fort Drum in New York state, as he signed a National Defense Authorization Act passed by Congress earlier this month.

"It's not enough to have American presence in space. We must have American dominance in space," Trump said, as he warned of the threat from China and elsewhere.

"Look at what they're doing, they have given me run-downs," he said in reference to security briefings. "I've seen things that you don't want to see what they're doing and how advanced they are."

"They want to jam transmissions which threaten our battlefield operations and so many other things"

"We'll be catching them very shortly," he said. "We will be so far ahead of them in a very short time, your head will spin."

He specifically mentioned a "new" Chinese military division that oversees space operations.

The spending bill contains a number of important provisions, including a prohibition on delivering F-35 Joint Strike Fighter aircraft to Turkey, a NATO ally unless they ditch Russian technology.

Trump has sparred with the country's leaders over the detention of a Christian pastor.

It also extends a restriction on US-Russian military cooperation, something the White House vociferously opposed. DM
