They should have had a Meson-equipped Orion standing by to collapse the Capella-Gamma Draconis node during the operation to destroy the Knossos. It's called covering all your bases. After all, they weren't entirely sure the Knossos could be destroyed in the first place.
Their plans seemed to be as follows:
Plan A: Destroy the Knossos
Plan B: Deploy the Colossus
Plan C: Collapse the Capella nodes (this plan wasn't formulated until much later)
They should have planned like this:
Plan A: Destroy the Knossos
Plan B: Collapse the Gamma Draconis node (after all, it's a worthless system)
Plan C: Deploy the Colossus
