Yep. Leaves lots of possibilities.
It's too early in the season to know anything about the motivations of "the cell"
They're supposedly Turkish right? Don't like Greeks? Maybe they're Kurds? Why the Defense Official chosen - something he did in the past? Revenge motive?
and I seriously doubt Fox would be stupid enough to intentionally inflame the situation.
Foresight is never perfect. Plus inflaming situations is not unknown on TV.
There must be something to the story that will explain why the Secretary of Defense was the target. The first two episodes made me think of "Lion's Game" by Nelson DeMille. Written pre-9/11 and a bittersweet read post-9/11.
