How Did The Romans Lose The War In The Jewish War

The Jews starting a conflict with the Romans was like poking a bear with a stick. How could that possibly end well? Upon receiving news of a Jewish revolt, the Romans were enraged and mobilized 60,000 professionally trained troops to take down the Galilee, where 100,000 were slain or became slaves. This demoralizing loss resulted in the realization of the Jewish leaders that the revolt was unwinnable, but this realization was long overdue. The Jews losing the war in 66-70 can be blamed on many things, however the retreat of refugees to Jerusalem proved to be a major flaw in Jewish war strategy. The refugees brought their radical views to Jerusalem and assassinated the more moderate Jewish leaders. Jew on Jew civil warfare was a major mistake
It was a fatal mistake for the Jews to kill each other and weaken their own (already inferior) army before the Romans even set siege to Jerusalem. The Jews fighting each other essentially did the equivalent of a pre-lab for the Romans in which they gave the Romans data on what procedures they best should take, set up the experiment, and set them up perfectly for success.
The Jews greatly increased the body count of themselves during the war and allowed the Romans to trample Jerusalem. One example of such stupidity and barbarity was when, because they knew that a siege was in the horizon, the Jews of Jerusalem had a multi-year food supply to keep the population fed. However, a radical faction of Jews set this entire reserve of food
Josephus writes “Vespasian had been a soldier all his life and was now a veteran; years before he had pacified the West and crushed the rebellion against Rome which the Germans had provoked; by force of arms he had added Britain, till then unknown, to the empire, so enabling Nero’s father Claudius, who had not lifted a finger himself, to celebrate a triumph.” Vespasian’s tactic of taking out Jewish strongholds such as Galilee and Jodapatha to punish the Jewish population (without ever touching the much more reinforced Jerusalem) was brilliant and effective.
