People will worship the dragon:

Revelation 13:4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?

Although in chapter 12 it was revealed that the dragon, is the same as the devil, the same as the serpent, the same as Satan.

However, Revelation 13:4 indicates that they worship the dragon, it doesn't say they worshipped Satan.

It is the same being, but with a different title.

Could they be worshipping the dragon as a different name, not realizing that it is Satan?

Can the dragon be Allah?

Can the worshippers of Allah be actually worshipping the devil, without realizing it?

The fruit of the dragon appears much the same.

His seat, that he gives the beast, is seen in chapter to be in Pergamos, in what is modern day Turkey, which is Muslim.

The Muslim empire was gigantic, and while it was ruled from Turkey, it suffered its mortal wound, a 100 years ago.
