Before the Obama-Clinton Administration took over: Libya was stable, Syria was under control, Egypt was ruled by a secular president and an ally of the United States, Iraq was experiencing a reduction in violence, the group that would become what we now call ISIS was close to being extinguished, and Iran was being choked off by economic sanctions.
Fast-forward to today: Libya is in ruins, our ambassador and three other brave Americans are dead, ISIS has gained a new base of operations, Syria is in the midst of a disastrous civil war, ISIS controls large portions of territory, a refugee crisis now threatens Europe and the United States, terrorists have gained a foothold in the Sinai desert, Iraq is in chaos, and ISIS is on the loose. ISIS has spread across the Middle East, and into the West.
