It's a very good question, and one that almost has no answer. You're talking about opportunity costs. What is lost by continuing to invest in this if prices rise on this relative to existing alternatives and capabilities that different platforms provide you, relative to political and strategic considerations, and relative to the economic, industrial, and technology considerations that are all involved here?
I don't think anyone knows. This is one of the first times Canada has ever gone down the development path. Historically, Canadian investments for new platforms have largely been based on the principle that we won't buy them until they're mature and someone else has them flying. That provides some degree of guarantee of relative security about costs and capability. There are a lot of examples where we started down the path and then pulled out of it early on.
On this model of the JSF or F-35, the consortium we bought into early on looked like it was going to play out then. Unfortunately, the future never fits our past, and it should have been recognized as a gamble. But once you start to add political, strategic, and other considerations, you essentially get trapped and can't escape.
