Broken Hearts and Minds; Done bombings as Caliphate Flying Recruiters

Since America stopped defending Kurdistan and attacked the Islamic State Caliphate, IS recruiting has jumped to 6000 a month which is 200 a day.

The key word here is counter-productive.
Unless you like building up the Jihadi Army of your dear Caliph?

 '... it is completely unsuccessful from the standpoint of destroying ISIS, but it’s an enormous success story for ISIS. It is actually helping the Sunni Islamists recruit new people – more than a thousand every month from across Asia, Africa, and the Middle East.'

So the US strike which killed 300 IS, further bids at 400 as a one off sounds a good months work until you do the maths and find out recruits have jumped to 200 a day because of the bombings.
That was one and a half days recruiting.
Some one is doing well out of this.

It would be cheaper to just open an Islamic State recruiting Office outside of the White House.
