Extending earlier investigations, we analyze the quasi-elastic
scattering of strongly interacting electroweak bosons at high-energy
e+-e- colliders. The three processes e+e- → bar-nu nu W+W-, bar-nu
nu ZZ, and e-e- → W-W- are examined at a c.m. energy of 1 TeV for
high-luminosity runs. The expected experimental error on the
scattering amplitude, parameter-free to leading order in the chiral
expansion of the WW interactions, is estimated for 1 TeV colliders at
the level of ten percent, providing a stringent test of strong
interaction mechanisms for breaking the electroweak symmetries.
