I pretty much agree with Scout101
. The plan seemed incredibly convoluted. What I don't understand is why the Breen didn't merely make detailed scans of the ships engines and then destroy it? The Tzenkethi were already shown to have the ability to create short, stable wormholes. Adding what the Breen learned from the downed ship would've only made that program even more successful.
It just seems that the only reason the Federation is still standing is because the Typhon Pact doesn't have a coherent foreign policy and military strategy.
