Who has been responsible for the events in the U.S. in recent years that are considered to be terrorism? How many were carried out by refugees or other individuals from the seven countries listed in the travel ban?
None of the deadly events that have happened in the U.S. in recent years were carried out by refugees. According to a report by the CATO Institute:
“Of the 3,252,493 refugees admitted from 1975 to the end of 2015, 20 were terrorists, which amounted to 0.00062 percent of the total. In other words, one terrorist entered as a refugee for every 162,625 refugees who were not terrorists. Refugees were not very successful at killing Americans in terrorist attacks. Of the 20, only three were successful in their attacks, killing a total of three people and imposing a total human cost of $45 million, or $13.84 per refugee visa issued. The three refugee terrorists were Cubans who committed their attacks in the 1970s and were admitted before the Refugee Act of 1980…” (Nowrasteh)
The recent Executive Order banning entry to the U.S. from certain countries lists these countries: Libya, Sudan, Yemen, Somalia, Syria, Iraq and Iran. (Levenson)
The major incidents in the U.S. in the past 25 years that have been termed terrorism, along with their perpetrators and countries of origin, are the following:
Of those who were foreign nationals, most were in the U.S. on work visas or tourist visas, which do not require the rigorous vetting process that is completed before admitting refugees.
