Who said I was offended? I just pointed out that the terms of the truce were either not thought out well, or unfairly slanted towards Rome. Besides, your solution would'd work either for similar reasons:
A) We don't all agree on what constitutes being Christians,
B) We don't all agree on our "being on the same path", or even what that path is,
C) We don't all agree on what the core problems are in Western civilization,
D) We don't all agree on what the solutions are to those problems, and
E) Some of us might think that the others are actually contributing to the problem with their proposed solution.
Hence, the efforts towards evangelizing by some or all parties. If you don't think your chosen faith offers the only road to salvation, and isn't a must-have for everyone else, you might as well hang it up right now -or at least consult the yellow pages and find a better one. I'm all for forging friendships and (limited) alliances. I'm just convinced we shouldn't deny (or compromise) Christ's lordship for the sake of human relationships.
The Orthodox church of course thinks she has the best approach, but we in no way, no how, make any claim on salvation as only found with us. We don't even say that all Orthodox are saved.
