Washington (CNN) President Donald Trump has signed off on a new national counterterrorism strategy, articulating his administration's vision for how the US should confront terrorist threats at home and abroad.

The new strategy document offers a broad strokes blueprint for how the Trump administration will and already has approached the threat of terrorism, from targeting terrorists at their source to beefing up efforts domestically to tackle the threat of homegrown terrorism.

In unveiling the strategy on Thursday, national security adviser John Bolton described the new strategy as a sharp departure from President Barack Obama's approach to confronting terrorism, emphasizing the Trump administration's recognition of the threat as one rooted in radical Islamist ideology.

"Radical Islamist terrorist groups still represent the preeminent threat to the United States," Bolton said. "We recognize that there is a terrorist ideology that we're confronting. And I think it's long been the President's view that without recognizing that we're in an ideological struggle, that we can't properly address the terrorist threat."

The strategy document does not direct resources or call for additional financing, rather laying out the Trump administration's broad counterterrorism framework. Bolton said the strategy involves "isolating" terrorist groups from their networks of financial support, bolstering US allies' counterterrorism capabilities and improving US infrastructure and preparedness, among other points.
