Usually when people discuss boycotts of international sporting events there is always a contingent that objects with that you shouldn't mix sports and politics or that sporting competitions "build bridges". It appears no one believes that anymore? Perhaps no ever did and merely used it to excuse the boycott's target? Personally, I think that you indeed should mix sports and politics and that repressive countries like China, Israel, Saudi Arabia, Eritrea, etc, should be boycotted. Their leaders care about international prestige and boycotts robs them of that. So this is a good move by the US. Though more consistency in who the US condemns for human rights violations would be nice.
