The Gulf States are extraordinarily suspicious of Iran for good reason. They view Iran as meddling in their affairs. They have seen Iran level asymmetric attacks against their facilities or their interests.

We can't discount how scary and shaken not just the Turkish government is, but Turkish society is. Imagine if you had some rump group of military officials here in the United States who started flying off with F-16s or other artillery and were taking shots at government buildings, and people were killed and injured. People would be scared and rightfully so.

It continues to be my strong belief that the way we are going to make sure that everybody feels a part of this global economy is not by shutting ourselves off from each other, even if we could, but rather by working together more effectively than we have in the past.

Ultimately, I remain optimistic about not just America's future, but the direction that the world is growing.

It is the kindness to take in a stranger when the levees break; the selflessness of workers who would rather cut their hours than see a friend lose their job which sees us through our darkest hours. It is the firefighter's courage to storm a stairway filled with smoke, but also a parent's willingness to nurture a child, that finally decides our fate.

There's no question that a lot of Americans on both the right and the left are expressing some fears and frustrations about the dislocations brought on by globalisation. Many of those frustrations are legitimate and they need to be addressed.

I am convinced that whenever we exaggerate or demonize, oversimplify or overstate our case, we lose. Whenever we dumb down the political debate, we lose. For it's precisely the pursuit of ideological purity, the rigid orthodoxy and the sheer predictability of our current political debate, that keeps us from finding new ways to meet the challenges we face.
