What I really don't understand in this story is, American secret service agencies found critical information on ISIS that could probably help take them out. ISIS are a bunch of misfits and do not have anything remotely near secret agents or even normal level intelligence.
So with this important bit of information, rather than using it with allies to take out ISIS, they sat on this information instead and at some point thought hmm let's share this with Trump.
As much as I dislike Trump, this is the biggest piece of BS I've heard. Logically, it makes no sense. Historically, it makes no sense. Critical information has always been shared with allies asap to help take the enemy down through coordinated attacks.
Maybe the rumours of Baghdadi being a Mossad agent are true and that was the information that was leaked in which case allies would be pissed.
