From a reader:

I wouldn’t try it. That is essentially what happened in one of the Seminole Wars, when Chief Osceola was captured during a truce. Result: the general who violated the flag of truce was denounced for his treachery, and Osceola became both the mascot of Florida State University and the namesake of the county where EPCOT Center is located.
Two hundred years from now who wants to see a college football team named the Jihadis, with a turbanned Osama cheering on the sidelines?
