President Donald Trump on Wednesday announced that the U.S. would send $100 billion in aid to its military and its allies in the coming years to help fight the Islamic State of Iraq and Syria (ISIS) terrorist group.

Trump announced the new assistance in the Rose Garden of the White House, saying it will go toward the Pentagon’s $500 million military and intelligence mission in Afghanistan.

Trump said the money will also go toward buying more of the country’s military equipment, as well as supporting its air force and navy.

“We have been the strongest nation on earth, the strongest military, and we will be again, because we are stronger,” Trump said.

Trump’s announcement came after a meeting with Defense Secretary Jim Mattis on Wednesday, in which he called for “greater stability and security” in the Middle East.

The meeting also included Mattis, Defense Secretary James Mattis, Homeland Security Secretary John Kelly, and Army Secretary John McHugh.

The new assistance will come as the Pentagon is grappling with a surge of foreign fighters, a surge in terror attacks, and a string of terrorist attacks across the U,S., Canada, Europe, Australia and New Zealand.

“I think it is time for us to be the strongest, most secure, most effective military force in the world,” Trump told reporters in the Oval Office.

The administration has struggled with the fallout from the Sept. 11, 2001, terrorist attacks, which killed nearly 3,000 people.

The government has struggled to put together an effective counterterrorism strategy to prevent future attacks.

It also has struggled in the face of ISIS attacks in Europe and elsewhere.
