There has been a good deal of comment — some of it quite outlandish — about what our postwar requirements might be in Iraq. Some of the higher end predictions we have been hearing recently, such as the notion that it will take several hundred thousand U.S. troops to provide stability in post- Iraq, are wildly off the mark. It is hard to conceive that it would take more forces to provide stability in post-Saddam Iraq than it would take to conduct the war itself and to secure the surrender of Saddam's security forces and his army — hard to imagine.

Sometimes corruption is slowed by shedding light into what was previously shadowed.

Putin is behaving in a very dangerous way. And Donald Trump sounds as though he would simply sit back and allow that to go on. I worry about where that would end up.

Jobs are a priority for every country. Doing more to improve regulation and help entrepreneurs is the key to creating jobs - and more growth.

For the private sector to flourish, special privilege must give way to equal opportunity and equal risk for all.

The Western alliance should have supported the Sunni opposition against the Assad regime from the beginning. As far as Iraq is concerned, if it had stayed stable the way it was in 2008, IS would not have been able to expand in Iraq the way they did. The mistake was that Barack Obama withdrew the armed forces from Iraq too fast.

We are already seeing a degree of instability in the world because Obama seems to have consciously wanted to step back. Donald Trump is going to be "Obama squared," a more extreme version of the same thing.
