Placing anti-D3 branes at the tip of the conifold in Klebanov-Strasslergeometry provides a generic way of constructing meta-stable de Sitter (dS)vacua in String Theory. A local geometry of such vacua exhibit gravitationalsolutions with a D3 charge measured at the tip opposite to the asymptoticcharge. We discuss a restrictive set of such geometries, where anti-D3 branesare smeared at the tip. Such geometries represent holographic dual of cascadinggauge theory in dS4 with or without chiral symmetry breaking. We find that inthe phase with unbroken chiral symmetry the D3 charge at the tip is alwayspositive. Furthermore, this charge is zero in the phase with spontaneouslybroken chiral symmetry. We show that the effective potential of the chirallysymmetric phase is lower than that in the symmetry broken phase, i.e, there isno spontaneous chiral symmetry breaking for cascading gauge theory in dS4. Thepositivity of the D3 brane charge in smooth de-Sitter deformed conifoldgeometries with fluxes presents difficulties in uplifting AdS vacua to dS onesin String Theory via smeared anti-D3 branes.
