Led by germany no doubt.
For anyone unfamiliar with the very long historical development that led to the EU.

Scripture refers to a Kingdom in the future that is a reconstituted Roman Kingdom, comprised of 10 smaller kings.
These kings will turn against Israel in the future - leading to the great and final battle of Armageddon.
I wondered what could cause them to do this... before the Muslim invasion into Europe. I can now see the hatred that will dominate and lead to an attack in Israel.
Between now and then, the EU has to lose 18 members to get down to 10, for things to mesh with this view of prophecy.
And my view of these things may prove wrong.
