First, I did not read the whole article.
Second, it has been written about multiple times that many of the ISIS commanders have been fighting the US military since 2002 (some were even trained by the US military)....that type of experience is priceless. ISIS knows our tactics, our methods and our weaknesses.
These guys will never be easy to defeat until we reinvent ourselves. With Obama’s commitment to the military, that is not going to happen anytime soon.
ISIS did not get rolling until Obama, against all advice, cut and ran from a nigh stable Iraq. ISIS also could have been squashed two years ago if, again, Obama had heeded sensible advice. This is almost all on Obama (and his Secretary of State, whomever she may have been).
He is still asleep at the switch ...
