The Byzantine Empire’s long run — 1,100 years — may seem remote from the 21st century, but a reading of its history offers at least three timeless lessons.

The Obama administration should act multilaterally to bring humanitarian relief, suspend diplomatic relations, and work with local authorities in Libya's liberated cities.

The danger that Islamist groups may exploit a Libyan vacuum power is real, but no reason for the US to be silent.

For Pakistan, founded as a homeland for all Indian Muslims, the Sunni-Shiite divide is an awkward subject that many would rather ignore. But the rest of the world needs to pay more attention to this conflict.

There are three important US actions that could speed up Gadhafi's demise and stop the killing in Libya: recognize the newly formed national council in Benghazi as the government of Libya, provide assistance to the new Libyan authorities, and support the imposition of a no-fly zone over Libya.

True virtue is military virtue--that of our latest generation of fighters.

Much could be done now to shift that balance against the regime--and hasten the end of Gaddafi’s massacres--without escalating foreign military involvement and perhaps even without supplying weapons to the opposition.

The United States needs to remain an imposing force in Iraq in order for the violence to diminish.
