That's why I hope that humans will create different organisation after the war. Together with races which are more willing to cooperate. What would you say if after the ME 3 there would be a cold war between the old council and Human-Krogan-Quarian/Geth alliance?
I don't know if you're being sarcastic, but in case you are not, I must say that I find this highly unlikely, since both the Krogan and the Quarians are among the least dependable allies out there.
Krogan don't even care for their own people, much less for their allies. To make a comparison, the Krogan to the Council races is what carpet bombing is to a homing missile. Once you let them loose, they'll just try to kill anything that moves rather than focus on any kind of objective (other than the classic "kill them all!" kind of course.)
The Quarians, on the other hand, are the exact opossite of the Krogan. Remember, those spaceships are all they have, and although they have the most massive fleet of all the organics, most of them are old and/or in a bad condition, to put it mildly. Remember, all space encounters for Quarians would be putting their home at stake, and I'm sure they would think twice or thrice before endagering it.
And if you think the ones above are bad, think about what siding with synthetics against organics would mean for Humanity. They had a bad rep before the whole Saren deal; now, after the massive attacks by synthetics ( Reapers), geth would be shot on sight, no questions asked. That would mean open hunting season for all organics friendly to them as well.
