Why would God not have a prophet to confront the AC?
This is what he has always done with AC type leaders in the past.
Not only will the AC kingdom be like 10 toes of clay and iron mixed, he will be confronted by the 2 witnesses.
You complain of others having preconceived notions of prophecy.
 
Why would God need more then 7 years to complete the last years spoken of in Revelations?
You can't just stack up the various judgments and construct a timeline out of them.
If he wants to run them concurrently so be it.
