In my opinon, the white gold concordat was a blow to both sides. The  aldmeri dominion have the armoury, the weapon, the mages, the warriors, everything needed to get into a continental war (Tamriel is a continent). However, by signing the peace treaty, they can not show signs of agression against anyone living in an Imperial Province, in exchange that they do not worship Talos.

If Skyrim were to become independent, yes, worshipping Talos would be legal again, however they would be vulnerable to the Dominion's wrath.

Still, worship of Talos is very important. And yes, I think, that just like the US and England, they can both still be friends through a group that is devoted to stop the Aldmeri (NATO).
