  We show that the physics of D-brane theories that exhibit dynamical SUSY
breaking due to stringy instanton effects is well captured by geometric
transitions, which recast the non-perturbative superpotential as a classical
flux superpotential. This allows for simple engineering of Fayet, Polonyi,
O'Raifeartaigh, and other canonical models of supersymmetry breaking in which
an exponentially small scale of breaking can be understood either as coming
from stringy instantons or as arising from the classical dynamics of fluxes.
