WT-doctrine is full of holes on this issue. First, Satan is the snake in the garden (that is, the snake isn`t really Satan, but according to JW-doctrine, he is). But has the rebellion in heaven even taken place at this point? I thought the rebellion takes place when the disobedient angels take on humanly bodies, and walk the earth as giants, at a later date! And so, Noah has to build that ark and stuff. And the Bible doesn`t say anywhere that the disobedient angels have access to heaven after the rebellion, on the contrary, Jesus visits them in Tar-ta-rus (the deepest section of the underworld) when he is dead for three days, where they are chained up (well, at least some of them). They are chained up! It says nothing about them being free to access the heaven and the earth! And it doesn`t make any sense that Satan is "hurled down to earth" in 1914, if he had access to the earth before this. And was he hurled down in 1914? Not before? Doesn`t it say somewhere in the NT that "I saw Satan fall to earth like a lightning", or something like that?
The first "beast" had a deathstroke healed
Yes. The deathstroke healed, that is emperor Nero, who the Christians were still very scared of. They were afraid that he might have recovered from his wounds, or maybe even come back to life, to continue persecuting the Christians, after he had died. The beast is all about Rome (seven heads, Rome is the city surrounded by seven mountains).
