Well, actually Pike said that the FEDERATION was that "armada". But that was in a bar, late at night. The man was probably drunk as a skunk, having dismissed his cadets and facing down just the equally stoned wunderkind Jim Kirk...

Ya Pike looked sober but that made no sense at all lol. But that line about the Federation being a peacekeeping and humanitarian armada gets repeated all over here and memory alpha. I mean it sounds good, but what the hell is a peacekeeping and humanitarian armada? lol. Its like the United Nations, the Red Cross and the Navy combined in one.
The Federation is a sovereign state like the United States, not a peacekeeping organization like the United Nations. And it is definitely not an armada. You can argue that United States has an armada in its US Navy, but the United States itself is not an armada. Likewise you can say the Federation has an armada in its Starfleet, but the Federation itself is no armada.
And while the United States might participate in peacekeeping or peacemaking operations authorized by the UN Security Council, the US itself is no peacekeeping organization. It is still a sovereign state that can deploy its military forces to wherever it wants without UN approval.
The Federation has never even participated in any kind of peacekeeping operation that we have seen. Yes they sometimes mediate political disputes, but peacekeeping means risking your own soldiers to keep two warring parties apart. It would be like sending starships to the Klingon-Cardassian border to prevent attacks from either side and not just protecting whoever they are allied with at the time. The Federation only deploys Starfleet to protect its own interests, it does not risk its ships in peacekeeping operations. Nor does it have the mandate to. There is no Alpha Quadrant peacekeeping organization like the United Nations where planets can vote on whether or not to deploy armed forces to intervene in a dispute. The Federation, with its own prime directive cannot appoint itself the Alpha Quadrant police
And yes the Federation, like the United States does offer humanitarian aid for things like disaster relief. But again, nobody would refer to the US or any country in general as a humanitarian organization like you would the Red Cross.
