At the center of President Obama's strategy for dealing with the Islamic State is an empty space. It's supposed be filled by a 'Sunni ground force,' but after more than a year of effort, it's still not there. Unless this gap is filled, Obama's plan won't work.
Donald Trump tests the limits of campaign speech. He makes false statements and refuses to correct them. He attacks other religions and ethnic groups, inflaming domestic tension and foreign terrorist rage.
Foreign policy is about the execution of ideas as much as their formulation.
We haven't usually had to face the extreme questions about liberty and order because we're not a nation of extremists. We love freedom and good government both.
We're grappling with the same issue facing all advanced economies - how to revive growth and distribute its fruits more fairly. An America that can tackle that problem head-on can perhaps help revive a stagnant global economy.
Images sometimes capture particular periods in history. The unreachable green light, beckoning from across the bay in 'The Great Gatsby,' has become a symbol of the yearning of America in the 1920s.
2011 is one of those years that historians are likely to look back on as a 'hinge.' And the truth, at once frightening and exhilarating, is that we don't know yet which way the door will swing.
As so many writers know, the experience of creating an imaginary world is closer to dreaming than it is to normal, grit-your-teeth work. It's preconscious rather than conscious. Ideas fall into your head, and the book writes you, rather than the other way around.
CIA officers aren't idiots. They knew they were heading into deep water - legally and morally - when they signed up for the interrogation program. That's part of the agency's ethos - doing the hard jobs that other departments prudently avoid.
U.S. adversaries exploit power gaps. It's easier for Russia to invade Ukraine with irregular forces out of uniform, the so-called 'little green men,' than to send a conventional army that would challenge NATO.
Helping Wall Street regain confidence and stability was the last thing an angry public wanted in 2009 after the markets crashed. But without such support, markets can buckle and liquidity can disappear - often for decades, as has been the case in Japan.
Machiavelli did believe that it was better to appear to be good than to be good. If you're good, you're just too vulnerable, but if you appear to be good, you get all the benefits plus you can be sneaky and, when necessary, stab someone in the back.
The Chinese are planning a manned mission to the moon sometime after 2020, and subsequently, to Mars. The U.S. has abandoned that dream.
Empty political space will be filled by extremists unless the United States and its allies build strong local forces that can suppress terrorist groups and warlords both. When the U.S. creates such local forces, it must be persistent. If it withdraws from these efforts, as America did in Iraq in 2011, it invites mayhem.
Middle Eastern wars rarely end with outright victory and permanent stability, so the word 'settlement' may promise too much. At best, for many years, it may simply mean stable ceasefire lines, reduced bloodshed, fewer refugees, and less terrorism.
Training a reliable military force that adheres to Western norms and standards is the work of a generation, not a few months.
If you want better behavior from bankers, then make their financial incentives more like those in the hedge-fund world - where managers have 'skin in the game,' and their net worth is tied to their long-term performance.
European Muslims need to feel ownership of security, rather than viewing the police as an occupying army.
Thanksgiving is America's favorite holiday because it's a time when we put aside our cares, much as the struggling Pilgrims did nearly four centuries ago, and eat a gut-busting meal without worrying about the 'out years.'
Bob Gates has unusual standing in the debate about the Obama administration's foreign policy: He was defense secretary for both a hawkish President George W. Bush and a wary President Obama. He understood Bush's desire to project power and Obama's skepticism.
