From Dan, the bartender at Southside Louie's: "Guantanamo all-inclusive."
Not bad, although I might go with "Crusader George and the Infidels" (which the aforesaid bartender dismissed as "not clever.")
While the handle sounds a bit 1950-ish, that's not entirely inappropriate.
Strangely enough, I can't find a U.S. punk band named "The Enemy Combatants" or "War President."
What's the deal? Are there no teenaged, snot-nosed, politically-minded Red State punks willing to take a musical stand? What is happening to America's youth? :)
I didn't bother searching on "Long-Term Struggle Against Extremism" because it just didn't have a ring to it.
