The Trump Order mentions overseas-born individuals responsible for "various" acts of terrorist crime since 9/11, including citizens who enter the United States on visas or through refugee-receiving programs. The perpetrators of the 9/11 attacks came from Saudi Arabia, the United Arab Emirates, Lebanon and Egypt.
In September 2015 the Committee on Homeland Security reported that a group calling itself the Islamic State (ISIS) has inspired or ordered 60 terror plots or attacks in Western countries, including 15 in the United States.
There are 250 US citizens who are known to have joined Islamic extremist groups.
Cases of terrorism in the US since 9/11
These cases include those who are charged with terrorism or those killed in terrorist acts for jihad.
A number of major attacks in the United States recently were not carried out by citizens who entered the executive order. The list of attacks includes:
Shooting at Fort Lauderdale Airport (January 2017): A US citizen
Orlando nightclub shooting (June 2016): A US citizen of Afghan descent
Shooting San Bernardino (December 2015): A Pakistani-American, and a Pakistani
Chattanooga Shooting (July 2015): US-born Kuwaiti citizen
Charleston Shooting (June 2015): A US citizen
Boston Marathon Shooting (April 2013): Two Russian nationals from ethnic Chechnya
There are some nonfatal attacks by individuals from two countries on the banned list of countries.
According to the New America Foundation, 82% of terrorist incidents since 2001 were committed by US citizens and permanent residents. Since the 9/11 attacks, jihadists have killed 94 people inside the country.
Studies conducted by the Cato Institute show that Americans are 235 times more likely to die of ordinary murder than die of terrorist attacks by foreigners in the United States. Republican Sen. John McCain and Lindsey Graham also from the Republic said the presidential order "may be more helpful in recruiting terrorists rather than improving our security", due to signals being sent to the Muslim world.
But President Trump dismissed the argument on the grounds that America's enemies were outraged and its primary responsibility was keeping America safe. And his supporters fully agree. "Donald Trump says the move is only temporary and I believe it," said a resident in Staten Island, New York. "The only duty is to protect the American people."
