The threat of a so-called enemy within is the most 'severe, emerging threat' facing the US military on home soil, according to Congressman Peter King.

King, who is Chairman of the House Homeland Security Committee, claimed this week that the threat of radicalized Islamists who are also U.S. soldiers executing attacks on American soil has grown.

King's new report, released on Wednesday and quoted in the Daily Mail, said there were nearly three dozen ‘threats, plots, and strikes’ toward the U.S. military since 9/11 and that another attack by 'militant Islamists' is 'a severe threat.'

23 of the 33 public cases prosecuted or investigated since 9/11 have occurred since mid-2009, King told the press this week, a development he called 'part of the broader surge of homegrown Islamist terrorism.'

Why not have Muslim congressman investigate Catholic Church scandals, ala Peter King?

Focusing primarily on the 2009 massacre at Fort Hood in Texas, where Army Major Nidal Hasan allegedly killed 13 people and injured an additional 29, King pointed out that many of those killed were soldiers serving alongside Hasan.

King noted that although the FBI and Defense Department had both investigated Hasan's communications with now-deceased Yemini cleric Anwar Al-Awlaki, the radical Al Qaeda imam, the task force closed their inquiry in 2009.

King's report also included details of several thwarted plans or attacks by other members of the U.S. military.

But King's critics have claimed he is indulging in dangerous profiling.

Rep Mike Honda, a Democrat from California, wrote on the Hill’s Congress Blog on Wednesday that King's report may in fact target Muslim Americans.

Honda said: 'If the hearing’s date (Pearl Harbor’s 70th Anniversary) and its subject matter, the 2009 attack on Fort Hood Texas, are any indication, today’s hearing will go too far by singling out Muslim-American service members as the danger to our military communities.'

Over 6,024 Muslim military members have served in the U.S. armed forces since 9/11, and fourteen of those soldiers are known to have been killed in action fighting for the US.
