[Spoilers main] What if Dalton Greyjoy supported the Greens during the Dance of the Dragons?
I’ve been thinking about an alternate scenario where Dalton Greyjoy sides with the Greens instead of pursuing his own independent agenda. Could this significantly change the balance of power at Sea? I think Dalton commands the Iron Fleet, one of the most experienced naval forces in Westeros when it comes to raiding and naval warfare, while the Greens have the support of the wealthy Reach and Westerlands, but their navy does not directly match the Velaryons. So if the Iron Fleet worked together with the Green fleets, they could realistically challenge Velaryon dominance at Sea. I also keep thinking that sacking Driftmark and destroying the power of House Velaryon, who are the main obstacle to controlling the seas, would be very tempting for a Greyjoy, since control of the sea is not just about battles but also constant opportunities for raiding and plundering. On the other hand, the presence of dragons on the Black side would make any large scale naval operation extremely risky, and the Velaryons might still maintain their advantage through experience and organization even without a decisive battle
