American Born Muslims Are More Likely to Commit Terrorism Than Muslims From The Seven Banned Countries

Let's consider what President Trump said when he introduced his executive order barring immigration and travel from seven Muslim majority countries:

I am establishing new vetting measures to keep radical Islamic terrorists out of the United States of America. We don't want them here.

We want to ensure that we are not admitting into our country the very threats our soldiers are fighting overseas. We only want to admit those into our country who will support our country and love deeply our people.

Yet when we look at the terrorist attacks that have occurred in the United States since September 11, 2001 a good many of them were perpetrated by American born Muslims. Among them were the DC Snipers, the Fort Hood shooter, the Little Rock Army recruiter shooter, the beheading at the Oklahoma food processing plant, one of the San Bernardino shooters (which precipitated Trump to establish this policy) and the Orlando nightclub shooter. 

Over this same period, there were only two incidents concerning the countries affected by the ban. The perpetrator of the March 2006 car ramming at the University of North Carolina-Chapel Hill was born in Iran while the perpetrator of the Ohio State University car ramming was a Somali refugee.

Aside from the two attacks I've described, the foreign born who have perpetuated terrorist attacks in this country have been from Saudi Arabia, United Arab Emirates, Lebanon, Egypt, Pakistan, Chechnya, Kenya and Kuwait. This encompasses 9/11, the Boston Marathon attacks, the El Al counter shooting at LAX, the Chattanooga military shooting and San Bernardino. 

I'm not saying that immigration and travel from the seven countries in President Trump's ban shouldn't have extra scrutiny. However, if the aim here is to prevent terrorism I simply don't see how barring immigration and travel from Iran, Iraq, Syria, Sudan, Somalia, Libya and Yemen will accomplish much of anything. It seems to me that if we want to address Islamic terrorism we need to look on our own soil first.
