I can't say I know more than just the simplest facts about Bhutto but the news [Edit]that she has been assassinated is not good. Not at all. [Graphic photos, here. Be forewarned.]
The Islamists will see this as a victory. Murdering a candidate for office...a woman...is a victory for them. Their brutality has no bounds. As things appear to be working in Iraq, we need to keep in mind just who our enemy is.
Seen first at Captain Ed's place (along with his insightful analysis here), but it'll be discussed just about everywhere else on the net too.
Edit: My gold-bug internet acquaintance is saying that this will be the trigger for another World War in the same way that the assignation of Archduke Ferdinand was the trigger for WWI.
