We know now that the Xindi have been getting their marching orders from the Trans-demensional aliens, who want humans destroyed because they will be the driving force behind the formation of the Federation, and the Federation will bring an end to the Trans-demensional aliens' attempt to take over our dimension.

Yes, the TDA's have been messing with time, but do they have anything to do with the temporal cold war?

The temporal cold war seems to be being fought between the Federation, and the Future Guy. Both of these factions have helped Archer in his mission to save earth.

Whatever FG's long term plans are, he seems to need Archer around, at least for now, as much as the Federation does.

At the beginning of the series, FG was trying to destabilize the Klingon empire, but was willing to leave Archer and crew alone for the most part.

I hope the series runs long enough that we finally get to see what this temporal cold war is all about.

I wonder how important Archer is to FG's plans?
