"It would be difficult to overstate the hardship and dangers the first American advisory team lived through. Our Iraqi soldiers shared the danger."

I also survived an assassination attempt in January 2005. Had it not been for another interpreter in whom I placed my utter trust and confidence, with my life, I should not have survived my tour. This Iraqi interpreter, whom I will refer to as Abdallah, survived his own assassination attempt. He was later one of the first recipients of a Special Immigrant Visa, and came to live with me for the first 8 months he was in the United States. This man served U.S. forces in combat for 7 years, participating in the 2nd Battle of Fallujah during which he stormed buildings and accompanied advisers in the stack as we fought the insurgents room by room. He is a veteran of literally hundreds of missions, including Special Operation Forces anti-terrorist missions. He also served as an interpreter for a U.S. army general officer in Iraq. In sum, this man is one of the bravest and most dedicated men I have met in my life.

This is a man who has completely committed to the service of the United States. And despite all his service and bravery, he was still vetted extremely by the following agencies in order to get his Special Immigrant Visa: the DHS, the FBI, the DIA, the NSA, and the State Department. And he required sponsorship by a general officer.

His story at least has a partial happy ending. He settled in a town close to where I live. He married and bought a house. He became a U.S. citizen. He and his wife had a child. Several members of his family have joined him in our country. Some have found employment, others have started businesses. Theirs is an Iraqi story, but it is an American story, epic in scope and born out of a lifetime of combat and hardship, and tempered by virtue and courage.

Until Friday. The elected President signed an executive order banning people from seven countries, including Iraq.

The inclusion of Iraq, and of people already in the U.S., makes no sense. Iraq is – at least in name – an ally. We have American troops right now as I write this, working with Iraqi forces in combat against ISIS in/around Mosul. There are Iraqi interpreters right now risking their lives, their families, what treasure they might have, and their sacred honor – for the sake of the U.S. war in Iraq. The executive order signed by the President is ill-conceived, and misses its target. The extension of the ban to green card (recently reversed) and Special Immigrant Visas holders endangers our troops currently in contact, and all future troops who will need the services of interpreters, on whom their lives will depend.

It persecutes, without due process, men and women who served the U.S. in combat, and have already gone through the extensive vetting by our security and intelligence agencies. It provokes a fight with people who have survived the worst Al Qaeda and ISIS could offer, and with people who given a choice, chose America.

I was there on Jan 30th 2005, the first Iraqi free elections. I saw the Iraqis chanting and waving their purple-stained fingers in the air – despite the attacks by Al Qaeda to keep them from voting. I fought for democracy, and for people who are committed to democracy.

I did not fight, and bleed, to betray the people who hazarded all they have, for the sake of decency, for the sake of democracy.
