The Daniel prophecies intended for the future beyond the 2nd century b.c. are just as sketchy and open to interpretation as the ones in Revelation.
What is sketchy about Daniel chapter 2 ?
The huge political statue describes the rise and fall of world powers since Babylon [head of gold], followed by Medo-Persia [silver], Greece [copper], Rome [iron or iron-like rule], and down to our day of Anglo-American.
Verses [34,35,45,44] describe God's governmental kingdom as a 'stone'.
A stone that grows in size to become a 'great mountain' or mountain-like governmental rulership filling the whole earth.
Filling the earth with righteous kingdom authority by having Jesus, as crowned king of God's kingdom,
who will usher in global Peace on Earth toward men of goodwill.
