Based on a model of the {ital d}=3 SU(2) pure gauge theory vacuum as a monopole-vortex condensate, we give a quantitative (if model-dependent) estimate of the relation between the string tension and a gauge-invariant measure of the Chern-Simons susceptibility, due to vortex linkages, in the absence of a Chern-Simons term in the action. We also give relations among these quantities and the vacuum energy and gauge-boson mass. Both the susceptibility and the string tension come from the same physics: the topology of linking, twisting, and writhing of closed vortex strings. The closed vortex string is described via a complex scalar field theory whose action has a precisely specified functional form, inferred from previous work giving the exact form of a gauge-theory effective potential at low momentum. Applications to high-{ital T} phenomena, including {ital B}+{ital L} anomalous violation, are mentioned. {copyright} {ital 1996 The American Physical Society.}
