If the U.S. is going to put big numbers of boots on the ground in the Middle East to force democracy down its throat, I have an idea. Instead of sending your kids or mine, let's retrain and send our most excellent global holy warriors, the DEA. We don't need them here at home. The ATF can handle drugs and guns, the FBI can handle drugs and gangs and the Coast Guard can handle drugs on the oceans and international waters. (They're also not particularly effective at the big stuff anymore: All that wiretapping and intel assistance to the Mexican Navy hasn't put a dent in the corruption in Mexico. El Chapo, his two sons and El Mayo are still protected and at large.)
Back to McCain and Graham: Their plan is not really that different than Obama's. When you get to the last few paragraphs, if you make it that far, you'll see what their really calling for is just what Obama has been doing -- only rather than say they agree with Obama, they say they agree with the Iraqi prime minister (who also wants no big combat troops in Iraq.) McCain and Graham's plan to defeat ISIS in the present (not the afterlife for which they have a different plan) boils down to:
Iraq’s prime minister, Haider al-Abadi, has said that he does not want foreign ground combat forces to be introduced on a large scale. Neither do we. What we do want is additional U.S. troops to perform discrete tasks: improve and accelerate the training of Iraqi forces, especially Sunni tribal fighters; embed with and advise Iraqi units closer to the fight; call in airstrikes from forward positions; and conduct counterterrorism operations (My emphasis).
Other than racheting up the number of ground troops in Raqqa, McCain and Graham's plan for beating ISIS now is pretty much the same as Obama's plan. It's the afterlife, with their call to colonize the world by having large numbers of permanent troops in Iraq and everywhere else in the Middle East and Northern Africa after ISIS has been defeated that's different. Given that, their plan is just the usual political blustery.
