  Imposing electroweak scale naturalness constraints (low \Delta_{EW}) on SUSY
models leads to mass spectra characterized by light higgsinos ~100-300 GeV,
highly mixed top-squarks and gluinos at the 1-5 TeV scale and allows for m_h
~125 GeV. First and second generation squarks can easily live at the 5-20 TeV
scale, thus providing at least a partial solution to the SUSY flavor/CP
problems. For such models at the LHC, gluino pair production is followed by
cascade decays to t- and b-quark rich final states along with multileptons. The
reach of LHC14 with 300 fb^{-1} is computed to be around m_{\tg} 1.8 TeV.
However, the small magnitude of the \mu-parameter-- a necessary condition for
naturalness-- leads to a unique hadronically quite same-sign diboson (W^\pm
W^\pm) signature from wino pair production. In low \Delta_{EW} models with
unified gaugino masses, this signature yields a somewhat higher reach up to
m_{\tg} 2.1 TeV. The smallness of |\mu| implies that the ILC should be a
higgsino factory in addition to a Higgs factory, and a complete search for SUSY
naturalness seems possible for \sqrt{s} 600 GeV. Since a thermal
under-abundance of higgsino-like WIMP dark matter (DM) is expected, there is
ample room for an axion DM contribution. A thorough search for higgsino-like
WIMPs can be made by next generation WIMP detectors, such as those with
ton-scale noble liquid targets.
