"Any religion you like - one government - Rome".

This policy ran into problems in two instances - where religion and government were one and the same - Druidism and Judaism.

The Druids decided they could live with the Roman deal. Consequence: there are no Druids anymore and nobody really knows what Druidism was - but descendants of the Druids stand equal with the Germans and Romans at the top of the heap.

The Jews chose not to compromise. There are still Jews and the traditions have held firm, but they've suffered severely for that choice - under the Romans and their successors.

It should be noted that the second Jewish revolt (Bar Kokhba revolt) was extremely serious - one Roman legion disappeared from the record entirely and thousands from Turkey and elsewhere were given Roman citizenship so they could join the legions to fight the Jews.

Today Judaism seems to have assimilated the concept of separation of church and state and things are going better. A recent survey (I'd have to dig through the pile for yesterday's LA Times to get the reference) shows that more than 80% of Americans are "antisemitism free".

If only they realized that Arabs are semites too . . . .
