JJA4 - So the answer in your opinion would be - no, it's not worth it. Can Canada make do with what it has then? Why replace your Hornet fleet at all? Can you 'make peace' on the ground when your Hornet takes a SAM or AAM before it drop it's weaponry? Going in under a UN banner doesn't always make a difference to the bad guys, as a Sea Harrier and several others found out over the former Yugoslavia.
Presumably your view differs from your (current) Government's, when's your next election or Defence Review which might change that?
