It’s not a weapon, it’s an aeroplane.
I mean, sure, you ca put weapons on it, but you can also use it as, for example, a sensor platform to look for on the run criminals (http://www.lynnnews.co.uk/news/local/latest-local-news/marham-tornados-in-raoul-moat-hunt-1-669029)
Also worth remembering that weapons can be used in a purely defensive, rather than aggressive role, such as shooting down German flying bombs, like, er, the RAF did in WW2.
Edit:
Of course, if someone was looking to be offended, you would have thought they might have been more offended by the Lancaster bomber of the BBMF that keeps dropping poppies on remembrance parades? It’s been doing it for bloody years without upsetting anyone though…
