They'll more than likely just stop mentioning how great of a leader Putin is (or at least have Lana seriously tone down her praise of him and pick and choose any references she makes to him) while continuing to harp on how much better and more dominant of an athlete Rusev than anyone America can offer. As long as they play it that way, there's no reason for him to receive the Muhammad Hassan treatment. They took it much, much further with Hassan than they have with Rusev, and hopefully it taught them what kind of boundaries they should and shouldn't cross with this sort of stuff (although the Hassan character was getting all kinds of real-life heat for months and months before they finally killed him off.)
I wouldn't be surprised if they had Swagger go over Rusev now though, just to put a "feel good" touch on recent events. Kinda like how Austin was supposed to retain the championship against Kurt Angle at Unforgiven 2001, but because 9/11 happened two weeks earlier, they did the title switch (Angle being the American hero and all) just to end on a positive note what was their first PPV since the terrorist attacks.
