Sadly, it did not end well. Bar Kochba led them to disaster and 2,000 years of exile. And the Temple has never been rebuilt. It is debatable if the Jews had hung on through roman rule if the invading Muslims would have destroyed it. I think they would have, looking at their record of destruction in other occupied regions like Spain.
When the Patriarch Sophronius surrendered Jerusalem to the caliph Omar, the caliph didn't destroy the Church of the Holy Sepulcher, so my guess is that he would have spared the Temple if it had still been there, but there is no way to know.
Bar kochkba was inevitable after the Kitos war where Jews massacred gentiles civilians in cyrene and Cyprus.
And that was inevitable from the 66 to 69 revolt
All true. The Bar Kochba revolt was crushed and Judaism persecuted by the Emperor Hadrian, who seems to have something of a contingent among Log Cabin Republicans. Hadrian had to be talkied out of evacuating Dacia, but ended the short two or three year occupation of Mesopotamia begun by Trajan. His famous wall in Britain replaced some earlier structures and was begun almost immediately after his mother connived to get him the job. During the six years it was under construction his relationship with the Judeans fluctuated. In 130 AD his teenaged Greek catamite drowned in the Nile, leading Hadrian to start a cult throughout the Empire to worship his dead victim of pedophilia. He probably wasn't in a good mood when Bar Kochba started his uprising. After the Roman victory, old Jerusalem was mostly leveled and renamed Aelia Capitolina.
In the years following the revolt, Hadrian discriminated against all Judeo-Christian sects, but the worst persecution was directed against religious Jews. He made anti-religious decrees forbidding Torah study, Sabbath observance, circumcision, Jewish courts, meeting in synagogues and other ritual practices. Many Jews assimilated and many sages and prominent men were martyred including Rabbi Akiva and the rest of the Asara Harugei Malchut (ten martyrs). This age of persecution lasted throughout the remainder of Hadrian's reign, until 138 C.E.Jewish Virtual Library | Ancient Jewish History: The Bar-Kokhba Revolt
