The UFC's red hot 200 million dollar PPV needs Khabib to participate. What threats do they have if he walks? Strip his title? They've already destroyed the value of their own belts. Most people can't even name all their champions. Attack his reputation? He destroyed Conor. Conor didn't even have a good moment in the fight that they can replay. Sue him? You think a court in Dagestan is going to rule against Khabib? Or that Putin would extradite him to the USA? Withhold his money? He never has to worry about his livelihood again in Russia. Hell, Putin can write him the same check if he wants. Threaten that he won't make more? Remember that Russian mathematician who solved the Poincare Conjecture then turned down the million-dollar prize? He just shrugged and said he didn't like the mathematical community. Russians simply don't give a fuck.
