Now that the Democrats have recovered from the shock of Governor Sarah Palin's nomination as the Republican's candidate for vice president, they have suddenly discovered that her lack of experience in general-- and foreign policy experience in particular-- is a terrible danger in someone just a heartbeat away from being President of the United States.

For those who are satisfied with talking points, there is no need to go any further. But, for those who still consider substance relevant, this is an incredible argument coming from those whose presidential candidate has even less experience in public office than Sarah Palin, and none in foreign policy.

Moreover, if Senator Barack Obama is elected, he will not be a heartbeat away from the presidency, his would be the heartbeat of the president-- and he would be the one making foreign policy.

But the big talking point is that the Democrats' vice-presidential nominee, Senator Joe Biden, has years of foreign policy experience as a member, and now chairman, of the Senate Foreign Relations Committee.

That all depends on what the definition of "experience" is.

Before getting into that, however, a plain fact should be noted: No governor ever had foreign policy experience before becoming president-- not Ronald Reagan, not Franklin D. Roosevelt, nor any other governor.

It is hard to know how many people could possibly have had foreign policy experience before reaching the White House besides a Secretary of State or a Secretary of Defense.

The last Secretary of War (the old title of Secretaries of Defense) to later become President of the United States was William Howard Taft, a hundred years ago. The last Secretary of State to become President of the United States was James Buchanan, a century and a half ago.

The first President Bush had been head of the C.I.A., which certainly gave him a lot of knowledge of what was happening around the world, though still not experience in making the country's foreign policy.

Senator Joe Biden's years of service on the Senate Foreign Relations Committee is even further removed from foreign policy experience. He has had a front-row seat as an observer of foreign policy. But Senator Biden has never had any real experience of making foreign policy and taking the consequences of the results.

The difference between being a spectator and being a participant, with responsibility for the consequences of what you say and do, is fundamental.

You can read books about crime or attend lectures by criminologists, but you have no real experience or expertise about crime unless you have been a criminal or a policeman. Continued...
