But the Pact already sees
the Federation as a threat. Why else would they organize all those efforts to weaken and distract and destabilize the Federation, starting with the terrorist attack on Capella IV and the subsequent disruptions to the mining of vitally needed materials on Capella IV and Maxia Zeta IV, with the maneuvering to get Zalda to almost leave the Federation, with the disruption of trade between the Federation and the Klingon Empire.
And that's before
the sanctioned attack and stealing of slipstream in Zero Sum Game
, and before the Typhon Pact send an ambassador to deliberately
provoke the Andorians into leaving and to encourage anti-Federation sentiment.
Considering all of that, the Pact is lucky that the Federation is even still allowing them to send an ambassador. (Interestingly, there hasn't been any mention of a Federation Ambassador to the Typhon Pact, yet).
