That's possible. One of the dangers, one of the big problems that all armed forces, including the United States, face today is the pace of technological development. How do you make decisions? We gambled in the past that the technological developments' span was 10, 20, 30 years. If you look back at the history of the evolution of fighter platforms since World War II, you've watched it shrink from 20 years of new platforms to technology shrinking and the ability then to add on a modular plug in new technologies.
There's no safe answer to this. There is no clear answer, but there are other reasons besides the stealth issue involved here as to why the F-35 is the only option for Canada.
