Now, we could be chilling all along and have an united front against non-European menaces.

All Europe would be the "Tertia Roma".

>be Roma, the Eternal City
>found an empire-civilization that rules the Mare Nostrum
>even your most bitter enemies admire your civilization
>in peaceful times you can chill with them and commerce flourish
>somehow they never adopt your civilization despite how much they like it
If Romanization had triumphed according to picrel, now all Europa would be Roma, we'd be speaking Latin and having temples to the 12 Olympians even in Svalbard (Norway).
