You cannot look at things by modern nations, etc.
Regarding the Power Point in the one link shows where the ten tribes were. Germania, not Germany, is laid out
here. The Netherlands were part of the Roman Empire at one time and part of Germania as well. On the chart you see at least three of the tribes having been in that area.
The Germans did conquer a lot of the Roman Empire after the fall and were for a long time the military might of Rome.
Being 9 sits fully within the prophecy. Per Revelation 7 heads with 10 crowns.
The Little Horn also is shown coming out of the Greek Beast and a toe, so Greece is one of the nations.
At Mid Trib, Germany and Russia attack Israel. Neither have ever been friends of Israel. They have been allies of the Muslims.
But, the EU, under the AC, will attack the Muslim nations per the AC treaty.
I think the warm and fuzzy to Muslims is going to turn violent soon.
Also, the power of the east islands, which I believe means the US and Great Britain, will stop the advance of the AC army, who will then conquer Israel, breaking the treaty at Mid Trib.
Now, some other countries are talking about leaving the EU. That, I believe, will move prophecy along more quickly.
