ISIS versus everyone else

So with the potential for air strikes against this shadowy force increasing day by day it must be time to start a thread on the subject?

Hezbollah don’t like them, but they aren’t going to strike at them, so it will be down to the US to support the Iraqis and then get blamed for whatever happens after.

To my mind, having a CAS presence 24/7 over the battlefield is the only way to go.

We have moved beyond a few armed Cessnas and a handful of Russian attack helicopters now, and it must call for heavy, sustained round the clock aerial bombardment with all the precision possible.

Can the Iraqi security forces effectively operate with the USAF assets? Are the US going to tell the Iraqis all the intelligence they are gathering in the area (exposing their reconnaissance assets to unwanted scrutiny) and to what extent have the Iraqis been operating with American attack aircraft in the past?

What do the US have that will allow significant surgical strikes to take place without flattening whole city blocks (as is the traditional OP)?
