CHANGE: Donald Trump Offers Michael Flynn Role as National Security Adviser.

His arrival at the White House would follow a military career and post-military life marked by periods of controversy.

In statements and writings, Gen. Flynn has said the U.S. needs to appreciate the scope of the threat from radical Islamists who want to destroy the country. “We’re in a world war,” he wrote in a book published this summer. “But very few Americans recognize it, and fewer still have any idea how to win it.”

During his 33-year career in the U.S. armed forces, Gen. Flynn made his name as a widely respected Army officer known for his candor and unorthodox sensibilities about intelligence and military operations. The 57-year-old retired general served in top roles across the military, including as director of intelligence for the Joint Chiefs of Staff and intelligence adviser to Gen. Stanley McChrystal in Iraq and Afghanistan.

By the end of his military tenure, he had become a maverick within the ranks of the normally deferential and apolitical corps of “general officers,” the military’s top-ranking officials.

Flynn is going to rankle all the right people — in Washington and around the world.
