It is argued that the spontaneous breakdown of global supersymmetry is consistent with unbroken Poincaré invariance if and only if the supersymmetry algebra "A=0" is understood to mean the invariance of the dynamical variables ø under the transformations generated by the algebra, i.e. [A,ø]=0 rather than as an operator equation. It is further argued that this "weakining" of the algebra does not alter any of the conclusions about supersymmetry quantum field theories that have been obtained using the original (stronger) form of the algebra.
