General Austin's testimony before the Senate Armed Services Committee last week about the condition of our War against ISIS was so bad that at least one Senator wondered if he was pulling her leg.
When General Austin was asked by the Senate how many Pentagon-trained fighters remained after spending $42 million the results were embarrassing.

“We’re talking four or five,” General Lloyd J. Austin III told the Senate Armed Services Committee on Wednesday. Austin heads Central Command, which runs U.S. military operations in the Middle East and South Asia, a position made famous by former General David Petraeus. Austin conceded that the rebel program is “off to a slow start.”
“That’s a joke,” Kelly Ayotte, the New Hampshire Republican, responded.

You would think that with results in Syria that spectacularly bad, that the Pentagon simply couldn't do any worse.
But you would be wrong.

On Friday the Pentagon sent another 75 U.S.-trained rebels into Syria.
So confident was the Pentagon in this new batch of fighters, that the headline this morning was With fight against the Islamic State in Iraq stalled, U.S. looks to Syria for gains. That headline should a) give you an idea of just how poorly we are doing in Iraq, and b) shows just how much they are counting on the Syrian effort.
So maybe we shouldn't have been surprised when this happened.

Pentagon-trained rebels in Syria are reported to have betrayed their American backers and handed their weapons over to al-Qaeda in Syria immediately after re-entering the country.
Fighters with Division 30, the “moderate” rebel division favoured by the United States, surrendered to the al-Qaeda-affiliated Jabhat al-Nusra, a raft of sources claimed on Monday night.
A statement on Twitter by a man calling himself Abu Fahd al-Tunisi, a member of al-Qaeda’s local affiliate Jabhat al-Nusra, read: "A strong slap for America... the new group from Division 30 that entered yesterday hands over all of its weapons to Jabhat al-Nusra after being granted safe passage.

If we just wanted to arm al-Qaeda we didn't have to go through middlemen. We could have done it cheaper by going directly to them.
Amazingly, the Pentagon has decided that this no longer matters.

Rather than subjecting rebels to repeated rounds of screening before and during their training, U.S. officials might restrict vetting to unit leaders already in the fight. “The key thing is getting them some [expletive] bullets,” one U.S. official said.

Oh yes. Getting "them" some bullets. If by "them" you mean al-Qaeda jihadists.

Maybe this is why former CIA Director David Petraeus said that we should "use al-Qaeda" against ISIS. We've already given them enough of our weapons.

In fact, arming jihadists has been our most successful strategy of the Syria conflict so far. Consider this article from early 2013.

With help from the C.I.A., Arab governments and Turkey have sharply increased their military aid to Syria’s opposition fighters in recent months, expanding a secret airlift of arms and equipment for the uprising against President Bashar al-Assad, according to air traffic data, interviews with officials in several countries and the accounts of rebel commanders.

Thanks to Snowden's whistleblowing, we know that the CIA was $1 Billion a year training approximately 10,000 rebel fighters, and sending weapons to Syrian rebels that all too often fell into the hands of al-Qaeda and ISIS.

Obviously we are too strict with who we give weapons too. We've also been too strict with which "moderate rebels" we train.

Abu Omar al-Shishani, the red-bearded face of ISIS terror lately described in such headlines as ‘Star pupil’: Pied piper of ISIS recruits was trained by U.S. for the fact that he received American military training as part of an elite Georgian army unit in 2006 and after, did not stop playing for “team America” once he left his home country in the Caucuses. He actually enjoyed US backing and American taxpayer largesse as late as 2013, soon after entering Syria with his band of Chechen jihadists.

We've spent so much time and money training and arming the fanatics that we are at war with, that pretty much everyone in the Obama Administration and Pentagon should be fired for gross incompetence....assuming that the objective is to actually win this war and make America safer.
Is it any wonder that 82% of Syrians blame the United States for ISIS? They have a good point. Unlike people in the United States, they have first-hand knowledge of the situation, rather than the official government lies that we are being fed.
If we keep training and arming the people who want to kill us, is there any hope that this war can ever end?
If we are to blame for ISIS, then we've also got a big hand in creating the refugee crisis.
