CEDRIC LEIGHTON, FMR. AIR FORCE COLONEL: Every single thing is based on having iron clad intelligence on the target and on exactly where the girls are and how the girls are being treated. What they also look at is how the guards operate, you know, what the routine is.

STARR: And that`s the kind of intelligence the U.S. simply doesn`t have at this point. And what if the girls have already been moved.

LEIGHTON: Each one is going to be in individual house, probably in different buildings, maybe even in different cities and that makes it really difficult to do a coordinated raid to go after them at exactly the same time.

STARR: Without all the raids at exactly the same time Boko Haram would have advanced warning the U.S. is coming after them.

So, what could the U.S. military offer? Well, perhaps drones flying overhead. To begin to monitor Boko Haram`s movements and communications. A first step to tracking them down. Barbara Starr, CNN, the Pentagon.

미군이 아직 보코하람을 습격하지 않았는데 왜 would have pp를 쓴 걸 까요? 아직 일어난 일이 아닌데 문맥상 만약에 습격이 동시에 일어나지 않는다면 ~할 것이다. 즉 미래나 현재에 대한 추측을 하는 걸로 보이는데 이 부분 설명 해주세요~
