I'll make a general comment, and it's one that I've talked about.
Because we've been effective at targeting their leadership, whenever the Taliban have concentrated and have tried to go conventional, if you will, they have lost in significant numbers. They have continued to resort to classic insurgent tactics, the use of IEDs and irregular means--that is, the use of children and women in suicide bombings. It is the only tool they have in their tool box. As we've seen, the unfortunate victims in this are not their target, which is us, but more often than not, the innocent civilians. Their tactics have not changed.
As to the tempo, we didn't see a huge spring offensive. But has there been a spike in the tempo since the poppy harvest was completed? Yes, there has.
