SEPECAT Jaguar

Having a bit of a nostalgic moment here.

Does any one else believe that retiring the SEPECAT Jaguar when we did in the UK was possibly one of the most short sighted decision ever?

Wouldnt they have been perfect for the work in Afghanistan, wouldnt their involvelment kept the GR9 harriers on the decks of the carriers?

Should the UK be looking at developing something similar again ?
