We reevaluate prospects for supersymmetry (SUSY) at the proposed International Linear $e^{+}{e}^{-}$ Collider (ILC) in light of the first two years of serious data taking at LHC: LHC7 with $\sim 5{\mathrm{fb}}^{-1}$ of $pp$ collisions at $\sqrt{s}=7\mathrm{TeV}$ and LHC8 with $\sim 20{\mathrm{fb}}^{-1}$ at $\sqrt{s}=8\mathrm{TeV}$. Strong new limits from LHC8 SUSY searches, along with the discovery of a Higgs boson with $m_h\simeq 125\mathrm{GeV}$, suggest a paradigm shift from previously popular models to ones with new and compelling signatures. After a review of the current status of supersymmetry, we present a variety of new ILC benchmark models, including natural SUSY, radiatively driven natural SUSY, NUHM2 with low $m_A$, a focus point case from mSUGRA/CMSSM, nonuniversal gaugino mass model, $\tilde{\tau }$ coannihilation, Kallosh-Linde/spread SUSY model, mixed gauge-gravity mediation, normal scalar mass hierarchy, and one example with the recently discovered Higgs boson being the heavy $CP$-even state $H$. While all these models at present elude the latest LHC8 limits, they do offer intriguing case study possibilities for ILC operating at $\sqrt{s}\simeq 0.25–1\mathrm{TeV}$. The benchmark points also present a view of the widely diverse SUSY phenomena which might still be expected in the post-LHC8 era at both LHC and ILC.
