Saudi-Iranian Tensions Widening Into Sunni-Shiite Cold War

The Saudi intervention in Bahrain has upped the ante in the
Saudi-Iranian cold war, crystallizing it into a wider Sunni-Shiite
schism in the Muslim world. Saudi Arabia has reportedly invoked a treaty with
Sunni-dominated Pakistan to secure troops to stabilize Bahrain and
its own eastern provinces. Riyadh has also asked Turkey to make
it clear to Iran that interference in the Gulf states will not be
tolerated.
