The Buzz Log What’s hot on Yahoo! Buzz™ (and why)...

Charlie Gibson interviewed Sarah Palin last week. In the life cycle of politics, that's a gazillion years ago. And yet, the ABC chat gave rise to a question that continues to ricochet across the Web: What is the Bush doctrine?

When Gibson asked the governor what she thought of the president's plan, she seemed not to know. Searchers appear to feel equally baffled. Over the past week, lookups like "bush doctrine," "bush doctrine text," and "bush doctrine wikipedia" have surged. Some searchers have taken the direct approach and simply asked their computers: "what is the bush doctrine?"

The answer, according to Gibson, is that the U.S. has "the right to a preemptive strike against any other country that we think is going to attack us." A popular article from Salon.com quotes a think tank writer as distilling the doctrine down to five simple words: "don't even think about it!" Exclamation point included.

However, as many esteemed members of the punditocracy have pointed out, the number of "Bush doctrines" has proliferated over the years. TIME cites one analyst as counting "as many as seven distinct Bush doctrines." Well, why stop at one when you can have many?

It remains to be seen how this buzz will play out—and whether it has any real impact on voters' impression of Sarah Palin. But in the meantime, we'll continue to watch in wonder as buzz keeps growing for the foreign policy question heard 'round the Internet.
