We show that the essential feature of SUSY naturalness is the presence of light Higgsinos with mass the closer to m(h) the better. The expected spectra gives rise to a unique same-sign diboson signature for LHC but a definitive test will require ILC with sqrt(s)~500-600 GeV. The perfectly natural Little Hierarchy might be a reflection of mismatch between PQ breaking scale and hidden sector mass scale fa<<m. In this model, ultimate detection of both an axion and a higgsino-like wimp is expected. A ton-scale noble liquid detector should probe the entire model since the lightest Higgsino always contains a non-negligible gaugino component.
