The ${K}_{L}\ensuremath{-}{K}_{S}$ mass difference provides a stringent constraint on the mass (${M}_{R}$) of the charged right-handed gauge field occurring in a "manifest" left-right-symmetric electroweak theory, yielding ${M}_{R}\ensuremath{\gtrsim}1.6$ TeV. Taken in the context of a grand-unifying gauge theory, e.g., O(10), such a large bound on ${M}_{R}$, along with the measured value of ${{sin}^{2}\ensuremath{\theta}}_{W}$, implies that ${M}_{R}\ensuremath{\gtrsim}{10}^{9}$ GeV.
