What do you guys think would have happened if Drogo would have never died? Think that Dany would have still got the dragons somehow? Think he would have eventually crossed, and if so, could they have won? Just reading Drogo's speech when he was telling Dany he'd go to the seven kingdoms makes me fukking tingly.
Dude said, "I will kill the men in the iron suits and tear down their stone houses. I will rape their wimen, take their children as slaves, and bring their broken gods back to Vaes Dothrak to bow down beneath the Mother of the Mountains."
Drogo was no joke, brehs.
It depends on Targaryen loyalists (not gonna get into that cause spoilers). Drogo with only his Dothraki would cause some trouble (really the common folk and lesser houses would get the worst of it) but the brilliant commanders of the bigger houses would see Drogo and the rest of his horse team wiped off the face of the realm.
