Query: Friendly heroes and idiot villains

Clancy's books are often uneven, but usually they are strong overall. When this one focuses in on the main plot halfway through, one can't help but notice that the villains are very poorly rendered. They seem like a hodgepodge of misguided keystone cop bad guys. Their logic and actions are so ridiculous that the book falls apart by the end, leaving the reflective reader very disappointed. If only real life terrorists and mad scientists were this incompetent, we could all sleep safely at night.
