Explicit CP violation in the minimal supersymmetric standard model (MSSM) radiatively induces a finite unremovable alignment between the Higgs doublets. This additional phase can be as large as the original CP phases in certain portions of the MSSM parameter space. Considering the specific case of the charginos, this additional phase is shown to induce a conceivable amount of CP violation near the would-be CP conserving points. Moreover, CP violation in the absence of this phase is smaller than that in the presence of it, and the former can never compete with the latter, however large $\tan \beta$ is.
