Ah, but there is a strategy: Appease Iran.
Note that Obama does nothing to arm the Sunni tribes in the west of Iraq, nor the Kurds in the north. These are the only two effective fighting forces facing ISIS. Instead, the Obama administration insists on supporting the Shia-dominated Iraqi regime, which has become a satellite of Teheran.
Further, Jordan cannot sustain their tempo of action because the necessary fuel and ordinance is not forthcoming from the Obama administration. And the most effective air force in the Middle East, the UAE, has left the field due to inadequate support from the US.
With regard to ISIS, the USA is not "leading from behind", but following Iran's lead.
Yes - there are those willing to take the fight to them with their own troops if we would just supply support...but Obama won’t.
