WebOne could solve the hierarchy problem by introducing new degrees of freedom that enforce such a cancellation as a symmetry requirement (rather than accidentally) which would suppress the couplings of the relevant operator. For example: Supersymmetry (SUSY). By the way, QCD doesn't have the hierarchy problem (apart from the strong CP-problem...).
