Honestly, I think any of these might be salvageable... Up until about the third or fourth paragraph when they turn into bog-standard action fare. (And yeah, "women with their quirky mixed signals who really need to be rescued by a good guy just so they know what they really want" has probably gotta go.)
The first one in particular, though its time-frame and/or setting would have to be altered, has potential. But I'd do it as a thriller rather than an action flick. If the hero wasn't some kind of quiet superhero, but more of an everyman who found himself on the wrong side of the fence with all sides against him? That could be interesting. And even sympathy-enducing.
Let's face it, most actual terrorists aren't the equivalent of special-forces supermen. They have a narrow skill set that makes the possibility of their accomplishing their given tasks seem like it falls on the side of possibility (ability to blend in with a crowd, language skills, and in some cases knowledge of explosives, weapons, or vehicles), fanatical devotion to their cause and/or a credible threat hanging over their heads, and a high degree of expendability.
