President Trump’s top national security adviser on Sunday warned North Korea against performing long-range missile tests as a “Christmas gift” — saying the US would respond with many “tools in its tool kit” if the rogue nation follows through.

Robert O’Brien said the US would “demonstrate” its “disappointment” if North Korean leader Kim Jong Un decided to recommence long-range missile and nuclear tests after the country warned it would give the US a “Christmas gift.”

“If Kim Jong Un takes that approach, we will be extraordinarily disappointed, and we will demonstrate that disappointment,” O’Brien said on ABC’s “This Week” Sunday.

“I don’t want to speculate about what will happen but we have a lot of tools in our tool kit,” he said.

President Trump previously made light of the threat — which is yet to eventuate — joking at his Mar-a-Lago resort in Florida that the gift could be a “beautiful vase.”

“Maybe it’s a nice present. Maybe it’s a present where he sends me a beautiful vase, as opposed to a missile test, right?” he told reporters.

North Korea suspended long-range missile tests and nuclear bomb tests in 2017.

But nuclear talks between the US and North Korea have stalled, with Pyongyang earlier this month declaring denuclearization was off the table.
