The President , Federal Bureau of Investigation ( FBI ) , Department of Homeland Security ( DHS ) , and the National Counterterrorism Center ( NCTC ) are the most relevant elements of the U.S. government to the threat of American Islamic extremism and each has taken steps to address and counter the issue . Since 9/11 the government has worked to improve information sharing " within the government , and between federal , state , local , and tribal law enforcement , as well as with the public . " The " If You See Something , Say Something " campaign , instituted by DHS and local law enforcement , was created to raise public awareness of the potential dangers . In August 2011 , the Office of the President released a strategy to counter violent extremism called '' Empowering Local Partners to Prevent Violent Extremism in the United States '' . The strategy takes a three-pronged approach of community engagement , better training , and counternarratives . The plan states : " We must actively and aggressively counter the range of ideologies violent extremists employ to radicalize and recruit individuals by challenging justifications for violence and by actively promoting the unifying and inclusive visions of our American ideals , " challenging extremist propaganda through words and deeds . The goal is to " prevent violent extremists and their supporters from inspiring , radicalizing , financing , or recruiting individuals or groups in the United States to commit acts of violence . " There are Muslim Americans speaking out against Islamic extremist activities , although the most common complaint is Muslim leaders do not speak out forcefully against Radical Jihad . An important voice is Dr. Zuhdi Jasser , the president of the American Islamic Forum for Democracy . Dr. Jasser testified before a House hearing on Muslim radicalization in the U.S. in early 2010 : For me it is a very personal mission to leave my American Muslim children a legacy that their faith is based in the unalienable right to liberty and to teach them that the principles that founded America do not contradict their faith but strengthen it . Our founding principle is that I as a Muslim am able to best practice my faith in a society like the United States that guarantees the rights of every individual blind to faith with no governmental intermediary stepping between the individual and the creator to interpret the will of God . Because of this , our mission is to advocate for the principles of the Constitution of the United States of America , liberty and freedom and the separation of mosque and state . We believe that this mission from within the “ House of Islam ” is the only way to inoculate Muslim youth and young adults against radicalization . The “ Liberty narrative ” is the only effective counter to the “ Islamist narrative . " Another voice , that warned of Islamic extremism before the September 11 attacks is Shaykh Muhammad Hisham Kabbani , chairman of the Islamic Supreme Council of America
