Eat. (Now there's something I haven't heard of for a while.)

Poutine.

All of my SG logo items are blanked now. By changing the logo, I filled the base for my group "Worshipful Company of Blackguards" with banners displaying the letters WCB. All have been blanked.

A lot would depend on how you define "defeat the Roman Empire". The Marines would be hard pressed to occupy the Empire; they'd have to cover territory from Britain to Egypt, and from Morocco to Turkey.

Now, the Romans didn't really have a law of succession, and respected military prowess for its own sake. After a decisive victory over a legionary force that demonstrated superior US technology, the Romans may well tell the Marines, "OK. You be emperor. Pick somebody." This was, after all, how emperors tended to be selected during the empire itself. There were few entirely peaceful successions. Has the Roman Empire been defeated then? I hope somebody in the Marines had high school Latin.

I see this more like a Manchu/Mongols vs. China scenario. The Manchu handily defeated China to found an imperial dynasty. That dynasty was almost entirely assimilated to Chinese culture. They "won" but not really. The mandate of Heaven: the gods must be in favor of whoever is winning.
