  "abstract": "In the post-LHC8 world-- where a Standard Model-like Higgs boson has been established but there is no sign of supersymmetry (SUSY)-- the detailed profiling of the Higgs boson properties has emerged as an important road towards discovery of new physics. We present calculations of the expected deviations in Higgs boson couplings $\\kappa_{\\tau ,b}$, $\\kappa_t$, $\\kappa_{W,Z}$, $\\kappa_g$ and $\\kappa_\\gamma$ versus the naturalness measure $\\Delta_{\\rm EW}$. Low values of $\\Delta_{\\rm EW}\\sim 10-30$ give rise to a natural Little Hierarchy characterized by light higgsinos with a mass of $\\mu\\sim m_Z$ while top squarks are highly mixed but lie in the several TeV range. For such models with radiatively-driven naturalness, one expects the Higgs boson $h$ to look very SM-like although deviations can occur. The more promising road to SUSY discovery requires direct higgsino pair production at a high energy $e^+e^-$ collider operating with the center-of-mass energy $\\sqrt{s}>2\\mu\\sim \\sqrt{2\\Delta_{\\rm EW}}m_Z$.",
