So there is one thing I don't get.
What does Dany think will happen after she wins?
The Dothraki are literal raping, pillaging savages who stand for everything she is against.
Once she has conquered Westeros they will have nothing to do and they will regress to their base impulses of raping and pillaging.
Will she send them back to Essos?
She didn't really think her plan through IMO.
