That's exactly right, Mr. Hawn. In fact, your experience as an ex-fighter pilot itself speaks volumes on your understanding of that fact.
We've been involved in many international consortiums in the past. In the case of many of these aircraft you've mentioned--the C-130J, the new C-17 heavy-lift transport planes, the Chinook helicopters--Canada benefited from participating in these programs with, most notably, the United States but other allies as well.
What would threaten our sovereignty, quite frankly, at a practical level, would be not having aircraft capable to defend our airspace, not having aircraft able to go up and meet any airborne threat.
You know full well, having flown CF-18s, that we need to be there to meet and greet any airborne threat--or any maritime threat, for that matter. This type of aircraft, the F-35, gives us that ability. That, first and foremost, is the responsibility of the Canadian Forces: to protect Canada and North America and to participate interoperably with other allies be they NATO or NORAD allies. That interoperability, that cooperative approach in both procurement and the defence of Canada, North America, and participating and international operations, is exactly what protects and promotes our sovereignty both at home and abroad.
