Washington – President Donald Trump’s choice to be the top U.S. military officer, retired Air Force Lt. Gen. Dan Caine, endeared himself to the commander in chief through his military call sign, “Razin,” during a meeting in Iraq years ago. Officials who have served with Caine described him Saturday as measured and apolitical.

The general made an impression in 2018 when he said, according to the president, that the Islamic State could be defeated in a week.

Caine, a three-star general whom Trump has praised since at least 2019, helped lead an operation in Iraq against the Islamic State during Trump’s first term.
