This is genuinely the only reasonable sovereignnty guarantee in the current geopolitical climate. We haven’t had a nuclear deterrent since the 80s, time to reaquire it. That’s just dreaming though, Canada simply lacks decisive leadership under any part, at least that’s the evidence of the last 30 years or so.
The F-35 deal pretty much has go too, we can’t but our frontline equipment from an adversary. The modernization of the Rafale and the Gripen E both say they have an enhanced ability to engage 5th gen jets, both could be a good call for Canada.
