  We study $\mathcal{N}=1$ models in which supersymmetry and $R$-symmetry are
broken spontaneously. We find that even the simplest well-known
O'Raifeartaigh-like models exhibit previously unnoticed phases and dynamics.
D-terms play an important role in the dynamics, creating a runaway behavior at
tree-level which is stabilized radiatively at a large scale. This leads to a
dynamically-generated hierarchy of scales. Additionally, this mechanism
generically leads to a spontaneously broken $R$-symmetry without fine tuning
the couplings of the theory. These are arguably the simplest known models that
break the $R$-symmetry spontaneously.
