It was an unstable year, yes, but one that the empire seemed to weather fairly well without a long civil war-hell, Vespasian became emperor by piggybacking off his success in Judea. I think we need something much, much much uglier. As in, an massive economic collapse during either a slow grinding civil war or else when the empire is trying to deal with abnormally powerful enemies on its borders, preferably with everyone in power but the emperor.
Like I said, the only people who can defeat Rome at this point is Rome itself. The Jews at this time for lack of a better term, were barbarian when compared to Rome. They were a tiny state right in the Middle of Roman manpower and had neither the population nor the capacity to mount an effective resistance against a united and determined Empire. I'm sorry Jason, unless you want to dramatically change history, the Jewsih revolt can
AT BEST delay the inevitable. Citing numbers of people doesn't help, just because they have 1.1 million people doesn't mean this will be compltely mobolized against the Romans, who if you want to talk numbers, have around 45-50 million people give or take.
But for the sake of argument, let's say the Jews are united. Firstly, slash that number in half to account for males. 500,000, slash that by about 66% to remove elderly and children and those unable to fight, thats around 150,000 left. Assuming that all of these men want to fight and that is being
EXTREMELY generous, you could only equip, maybe a third of them at best. You are down to about 50,000. Note that this army will be unprofession, poorly equip compared to Rome and will be facing superior numbers.
Verdict. Fucked.
Even if they defeat one Roman Army, they are going to be badly mauled and wont withstand a second. Please note I am being very very generous with numbers, and that is assuming the Jews are somehow united. Seriously, it's like modern day Cuba taking on the full might of the modern United States. They are going to lose.
