I had no clue how naive these gundam writers are. Terrorism isn’t going to stop just because some military intervention from outside. Even if the outside force fights both sides. In fact, what that often does is actually uniting the two enemies and make them fight against the outsider.
“…the REAL IRA stops their terrorism activities in Northern Ireland…”(snicker) I’ve been told that the IRA in real life (the really real IRA) had already stopped terrorism activities.
