Clinton was a leading advocate for the 2011 military intervention in Libya, which Obama has since called the biggest mistake of his presidency. Clinton also was an early supporter of arming the so-called moderate rebels fighting the government of Syria — a policy Obama ultimately adopted later, even though he opted not to launch a conventional military attack against Syria’s President Bashar Assad.
