Let's look at the first item:
Babylon overthrew Israel (more accurately, Judah)
Jeremiah is dated to the period of Josiah, 30 years before Babylon's campaign into Judah.
11 This whole country will become a desolate wasteland, and these nations will serve the king of Babylon seventy years.
12 "But when the seventy years are fulfilled, I will punish the king of Babylon and his nation, the land of the Babylonians, for their guilt," declares the LORD, "and will make it desolate forever.
Jeremiah 25:11-12, written ~30 years beforehand.
Afterward, Cyrus 'punished' the king of Babylon, and Babylon has been uninhabited since.
That is real history.
Jeremiah also proclaimed that the "messiah" would come from David's family:
"The days are coming," declares the LORD,
"when I will raise up to David a righteous Branch,
a King who will reign wisely
and do what is just and right in the land.
Jeremiah 23:5
Can you deconstruct this to invalidate it? Sure.
I'm not sure what you mean about the morality of the scriptures and a Taliban warlord however :) Obviously, you understand the historical events of the time regarding Joshua and Israel, juxtaposed to the teaching of Jesus?
It is said that "Jesus revealed who God is" to man; so extrapolating a moral conception from Joshua (for example) is repudiated by the writers of the NT.
