Syria, the country where the original King of the North was based, would be plunged into a vicious civil war during the latter part of the days.
How it that a prophecy? At the time of Daniel, the entire area was constantly in war.
Daniel 8 proves Daniel is not and is also part of much evidence that Daniel was not completed till about 200BC. Daniel discusses four world powers, agreed upon as Babylon, Medo Persia and Greece and Rome. However, only the first three are named in Daniel. The forth (Rome) that belongs to a time after Daniel was finalised was not named because Daniel is not prophetic.
