How will the US respond to the ISIS beheading?

foley-photo-syriaThe Islamic State of Iraq and al-Sham (ISIS) has responded to US attacks on Iraq with the brutal beheading of American journalist James Foley and a threat to execute another journalist, Steven Sotloff, if the US does not call a halt to air strikes. The militant group says the US is no longer fighting an insurgency, but an Islamic army, and a state that has been accepted by a large number of Muslims worldwide. But will the threat affect US tactics in Iraq?
