We show that theories in the confining, free magnetic, and conformal p
hases can break supersymmetry through dynamical effects. To illustrate
this, we present theories based on the gauge groups SU(n) x SU(4) x U
(1) and SU(n) x SU(5) x U(1) with the field content obtained by decomp
osing an SU(m) theory with an antisymmetric tensor and in - 4 antifund
amentals.
