The reason the US is footing the whole bill and no one else is helping (despite our god-awful government being just as keen to do this) is because any time aid to help insurgents is so much as mentioned, our social media lights up with vitriolic abuse towards the authorities.

Our government is now frightened to intervene because of the massive tide of hatred towards middle-east intervention.
