nope.
I mean, while Daeny is gathering troops to invade Europe, she is taking apart all the significant cities in Africa - the city with the wizards, the city with the slaves (unsullied?), and now the other city. all of those places were small dictatorships in the dessert, but had enough military to repel the dothraki clans from attacking them.
the dothraki had to go after relatively small agriculture and herding villages. but now that Daeny took the military forces from those cities, there is nothing stopping the dothraki from raiding them.

I should get the books.. I hate not knowing stuff.
