It is argued that, in the context of supersymmetry, the strong CP problem is most naturally seen as an aspect (particularly severe) of the whole complex of flavor-violating and CP-violating problems of supersymmetry. It is shown that certain approaches to solving these flavor problems also allow simple solutions to the strong CP problem. The idea of {open_quotes}flavor alignment{close_quotes} suggested by Nir and Seiberg allows not only flavor violation to be controlled but supersymmetric contributions to the {theta} parameter to be made acceptably small. Another approach to the flavor-violation problem, namely, low-energy supersymmetry breaking, allows another class of solutions to the strong CP problem to be viable. {copyright} {ital 1997} {ital The American Physical Society}
