Foreign policy is something Americans care about when the economy is good, and when it isn't, they hardly notice it. It's hard to worry about what happens in the Mideast when you don't have a job in the Midwest.

Our military leaders don't seize power in coups; our soldiers and sailors don't go on strike for higher pay or benefits; our armed forces don't weigh in on the political process. In return, Americans have a sacred duty to treat them honorably.

One of the lessons of Vietnam, which we failed to heed in the Iraq war and the Afghanistan surge, is that before you commit U.S. military forces to aid or assist, it is essential to know what you want them to achieve.

In politics, a picture is worth a thousand words.

Despite spending trillions of dollars and spilling the blood of thousands of Americans, we remain in servitude to Arab oil.

In foreign policy, the only thing worse than not doing something is doing something that fails or makes the situation worse.
