On March 28, 2011, nine days after the seven-month attack on Libya began and 10 days after saying it would last “days, not weeks,” Obama gave the nation televised assurance that “the task that I assigned our forces (is) to protect the Libyan people from immediate danger and to establish a no-fly zone.” He said that U.S. forces would play only a “supporting role” in what he called a “NATO-based” operation, although only eight of NATO’s 28 members participated and the assault could not have begun without U.S. assets.
