BAGHDAD —
As the United States and its allies look to fight the Islamic State in Iraq and
Syria, longtime adversaries with a common fear of the radical movement are
scrambling to see if they can cooperate to defeat the rising threat.
The
jihadist group known as ISIS has so far
thrived in part because its enemies are also enemies of one another, a reality
that has complicated efforts to muster a strong response to its rampage. That factor
has been a crucial consideration in war planning in capitals as diverse as Tehran and Washington , London and Damascus .
But the potential threat has also forced a re-examination of centuries old
tensions between Sunnis and Shiites, Kurds and Turks.
