The Tanakh is full of stories where the Israelites break with God and a new covenant/promise needs to be made to heal the break.

So something must have happened where the Israelites again broke with God, and it must have been something bad because God allows the Second Temple to be destroyed as a giant sign of divine disfavor, and then another, longer exile.

But then instead of God sending another prophet to save His people, which happens again and again in the Tanakh, He sends no one.
Not one prophet for 2000+ years. Why?
Has Judaism ever gone this long without hearing from God?
