“Gibbon says that the menorah is at the bottom of the Mediterranean. Israel should go get it.”
2. The “bottom of the Mediterranean” is a VERY large place. Even if you can somehow specify a box that’s 5 miles x 5 miles (and I doubt that), there have been over 1,950 years of silt being built up over it, so just going to find it will be a nearly impossible task. If it was so easy, it would already have been done.
Maybe before responding you should have gone to Gibbon to see what he says. You could have saved yourself some trouble.
It’s been speculated that the Menorah may be under Oak Island in Nova Scotia,
that the Knights Templar stashed it there. along with the Ark of the Covenant.
Unlikely, but who knows….
Before the FIRST Jewish-Roman war, the Romans had a problem that people were converting to Judaism (as we read in the first chapters of Acts) -- note that even the nephew and the daughter-in-law of the Emperor Vespasian were converts to Judaism (or more likely acolytes).
The Jews and Greeks were fighting each other in Caeasarea Maritime (Tel Aviv), the Decapolis (north-western Jordan today) and in Egyptian Alexandria as well as in Anatolia. The Jews were arguing with Nabateans and Samaritans.
Anyway, you can read in Josephus how Agrippa II who was Herod the Great's grandson and ruled over most of Judea and Galilee told the zealots etc. NOT to revolt as it would hurt the entire Jewish diaspora
There were 2 Jewish kingdoms (or 3 Jewish ruled areas) in 67 AD:
After the destruction of Jerusalem, the Judean kingdom remained under the Herodians - Jews were still allowed to live in Judea, but Jerusalem was a smouldering ruin
then the Jews committed genocide against the pagans in Cyrene and Cyprus during the SECOND Jewish-Roman war (called the Kitos war) = note that this genocidal activity is also noted in the Jewish encyclopedia as well as numerous Roman era works) and finally the Jews rose up again in 132 under ANOTHER "Messiah" - Simon Bar Kochkba (Simon, "son of the star" i.e. "son of God") and failed
after 132 the very term "Jewish" was considered linked to a treasonous sort and they were removed from their homeland
AT the same time the "Jesus-movement Jews" started jettisoning the "Jews" part of it, takin on the exonym "Christian" (or Nasrene in the east)
There was NOT a chance that there would be any "Jewish" kingdom as long as the eternal empire stood - so no question of a bargaining chip
When the Romans became Christian in 378 AD under Emperor Theodosius II, then this was just reinforced
There was a brief "Jewish" state in 614 AD when the Iranians conquered much of the Roman east and were aided by Jews in both Judea and in Egypt and rewarded them with positions of Authority
The Roman (whether headquartered in Rome, Milan or in Constantinople) would not envisage a Jewish (or Athenian or Gaulish) state unless the empire fell
