I've said it a hundred times,Girls in the Night Traffic but I'll say it again. If Jon Snow wants to rule Westeros he should just get a bunch of guns.

Reddit seems to have the same idea. A thread on the Game of Thronesfan subreddit r/gameofthrones asks the theoretical question: What would happen if a brigade of U.S. Army soldiers arrived in Westeros?

Another user explains how the military, after forcing every major army to surrender, would be able to set up defenses against the White Walkers.

Even if you're not into the relatively silly hypothetical, you must admit that Drogon wearing a bullet-proof vest would be pretty cool.
