From CBS News:

"If a tree falls in the forest and no one’s there to hear it, does that mean that it didn’t make a sound?" This was Mike Huckabee’s response when a reporter noted that a state newspaper had endorsed John McCain, calling Huckabee’s foreign policy experience unsettling. "The fact that they are not aware of, maybe, the experience that I  do have traveling to 41 countries, visiting with several prime ministers, having many trade missions and dealing with imagepolicy they may not be aware of, it doesn’t mean it did not happen, it may just mean they may not be aware of it," Huckabee continued.

"I also would remind people that what you would look for in a president is judgment. You look for the capacity to make decisions, and if you’ve been a governor, you’ve had more experience in actually making decisions and doing that across the broader battlefield than simply in the legislative body. Being able to pick an issue or two, focus on it, specialize in it, but maybe never have had the experience of looking at all of those issues and how they integrate together. In the executive branch, you don’t have the luxury of isolating issues, you have to integrate those issues and how they all function together."

Does Mike Huckabee have the experience to lead?

Mike Huckabee has as much experience as any other Governor who ever ran for President. Mike Huckabee has the leadership experience that comes with being an executive and has shown he can make tough executive decisions. He knows how to surround himself with good people, listen to advice, and make the best decision. He seems to be the only candidate with a clear grasp on the nature of this war as a radical religious mission of extermination and tyranny on the part of the terrorists. He believes in the Powell-Schwartzkopf doctrine of overwhelming engaging force, and fully Theodore Roosevelt (Wikipedia)stresses that military decision-making should be delegated to our commanders with "the blood on their boots and the medals on their chests." This doesn’t sound much like a Jimmy Carter, but more like Theodore Roosevelt. "Speak softly, but carry a big stick." (source)

Executive experience is considerably more
important  than foreign policy experience.
Mike Huckabee has that experience .
