Ten Kings of Revelation and the Great Tribulation

Ten kings of Revelation & Great Tribulation

In the Book of Revelation it discusses several reorganizations related to the final Beast power. Does Revelation 17:12 teach that the final Beast power will be made up of 10 (or 11) currently existing nations? What does the Greek show?  What did the old Worldwide Church of God teach?  Does Daniel 2:41-43 provide support for or against the idea of ten currently existing nations coming together?  What scriptures prove that the coming Beast power will be based in Europe?  Will any 'Israelitish' nations possibly be part of the ten kings of Revelation 17:12?  Why is the truth about Revelation 17:12-13 important to know?  Will Christians who believe something that the Bible does not teach be subject to the Great Tribulation of Matthew 24:21?  Why will those who insist  on something that the Bible does not be subject to not fleeing from the coming Great Tribulation?
