In a polarized region and a complicated world, the Islamic State in Iraq and Syria presents a unifying threat to a broad array of countries, including the United States. What’s needed to confront its nihilistic vision and genocidal agenda is a global coalition using political, humanitarian, economic, law enforcement and intelligence tools to support military force.

Libya is in civil war, fundamentalist armies are building a self-declared caliphate across Syria and Iraq and Afghanistan's young democracy is on the verge of paralysis. To these troubles are added a resurgence of tensions with Russia and a relationship with China divided between pledges of cooperation and public recrimination. The concept of order that has underpinned the modern era is in crisis.

Europe's failure to stem conflicts raging just outside its borders is calling into question the EU's focus on "soft power," centered on discreet diplomacy, economic incentives and in particular Europe's own example of former enemies working together to build common prosperity.

No. 1: Will there be a deal on Ukraine? The crisis in Ukraine has been a colossal failure of analysis and of diplomacy, with plenty of blame to share on all aides. The main victims, alas, have been the unfortunate Ukrainian people. As I've written before, I think the United States and the West played a key role in causing the crisis, mostly by failing to anticipate that Russia was going to respond forcefully and vigorously to what its leaders regarded as a gradual attempt to incorporate Ukraine into the West. 

Qatar is working to help free four Americans held hostage in Syria by various armed groups, a Gulf source familiar with the matter said on Monday, a day after the Gulf Arab state's diplomacy helped free a journalist held since 2012.

There are extraordinary elements in the present U.S. policy in Iraq and Syria that are attracting surprisingly little attention. In Iraq, the U.S. is carrying out air strikes and sending in advisers and trainers to help beat back the advance of the Islamic State of Iraq and the Levant (better known as ISIS) on the Kurdish capital, Erbil. The U.S. would presumably do the same if ISIS surrounds or attacks Baghdad. But in Syria, Washington’s policy is the exact opposite: there the main opponent of ISIS is the Syrian government and the Syrian Kurds in their northern enclaves.
