We show that, up to one exception and as a consequence of first order perturbation theory only, it is impossible that a large portion of the well-known family of breather solutions to the sine Gordon equation could persist under any nontrivial perturbation of the form utt - uxx + sin u = εΔ(u) + O(ε2), where Δ is an analytic function in an arbitrarily small neighbourhood of u = 0. Improving known results, we analyze and overcome the particular difficulties that arise when one allows the domain of analyticity of Δ to be small.
