The reality is that there are 17 different Intel agencies that compile their own assessments along with the added shared Intelligence received from the Israelis...
There's a snap assessment (as in we hit the target) and an in depth assessment (as in All the agencies submit their assessments graded by High to Low level of confidence...and then complie a Final Assement based on the information currently at hand).....
The DIA assement has been reported to be of a Low level of confidence and literally no other Intel agency seems to concur with it...
So do you go with the 16 other agencies and the Israelis (who have both close in drones and also reportedly "boots on the ground") of do you go with an assessment from DIA that clearly was leaked Before the actual Intelligence Final Assessment had been reached and produced...?
Basically, anyone buying the DIA product as the authoritative Final word on the matter is a fool..., which explains why CNN swallowed it hook, line, and sinker... (they're not the brightest bulbs in their makeup mirrors)....
