It just means we're winning
By all accounts, the violence will get worse the closer we get to the June 30th transition of power in Iraq, and this story is just the first of many more we'll hear about. It must be remembered that in all wars, the last ditch efforts of those about to perish always makes the situation look bleaker than it really is. What we have here are some desperate terrorists trying to derail the transition process by any means. So long as we stand firm and do not let these cowards dictate the fate of the country, you will see a stabilization of Iraq after June 30th, until it is time for the general elections scheduled for early next year, when we'll again see an uptick in attacks. This type of thing will occur for years and years, have no doubt, but with firm guidance and a resolve to finish the job, Iraq will become much more like Afghanistan than it is today.
