If you believe the administration boilerplate, you would think Obama's "J.V. Team" has been all but decimated. At various times the President has claimed that ISIS has been operationally, financially, and territorially diminished, and he regularly paints a picture of a terrorist organization on the verge of total collapse. Anyone with even the most feeble understanding of global events knew that was complete B.S., but it's the manure the administration has been shoveling.
Now, sadly, CIA Director John Brennan has testified that it is, in fact, hogwash. Whatever territorial gains we've made have had little impact on ISIS's ability to carry out attacks. In fact, those meager victories have done nothing to impair their operational reach, and have made them more determined than ever.
