Washington ( CNN ) -- Homegrown terrorism will be part of the United States ' National Security Strategy for the first time , according to President Barack Obama 's chief counterterrorism adviser , who called it a new phase of the terrorist threat . When the Obama administration unveils its National Security Strategy on Thursday , it will be the first time any president `` explicitly recognizes the threat to the United States posed by individuals radicalized here at home , '' National Security Adviser John Brennan said Wednesday . The strategy acts as a blueprint for how a White House administration intends to protect Americans . In the past , it has focused mostly on international threats . But a spate of terror-related plots in the United States recently prompted the Obama administration to include homegrown terrorism in the document , Brennan said . Earlier this month , Pakistani-American Faisal Shahzad was charged with trying to detonate a car bomb in New York 's bustling district of Times Square . U.S. Army Major Nidal Malik Hasan is suspected of fatally shooting 13 people at Fort Hood in November . Colorado resident Najibullah Zazi , an Afghan national , pleaded guilty in February for conspiring to detonate explosives in the New York subway system . And David Headley , an American citizen from Chicago , Illinois , is accused of providing surveillance in the Mumbai , India , terrorist attacks that killed 160 people . `` We 've seen an increasing number of individuals here in the United States become captivated by extremist ideology or causes , '' Brennan said . `` We have seen individuals , including U.S. citizens armed with their U.S. passports , travel easily to extremist safe havens , return to America , their deadly plans disrupted by coordinated intelligence and law enforcement . '' Brennan , who made his comments at the Center for Strategic and International Studies in Washington , said that as the United States has strengthened its defenses against massive attacks like 9/11 , al Qaeda has shown itself to be a `` resilient , resourceful and determined enemy . '' Brennan said al Qaeda is recruiting individuals with little training , attempting relatively unsophisticated attacks and seeking people living in the United States to launch such attacks . `` They are seeking foot soldiers who might slip through our defense , '' Brennan said . `` As our enemy adapts and evolves their tactics , so must we constantly adapt and evolve ours . '' Brennan did not provide any specific details about the president 's strategy for combating al Qaeda and its affiliates , but said it `` will require a broad , sustained and integrated campaign that harnesses every tool of American power , military and civilian , kinetic and diplomatic . ''
