If the goal is distance from the US, there is only one candidate. And it's the one that failed US security requirements in our fighter competition: the Rafale.
The Gripen fan club is a bit ridiculous. Having an American engine is not a minor vulnerability if you're worried about US policy.
But also, if we're going down the road of not fielding any US kit or integration, we're going to have a whole lot of problems immediately. An F-35 without American software updates is still useful. But a Gripen without missiles is less so. Point here is that our real vulnerability lies not in integration worries based on conspiracy nonsense. It lies on realities like the majority of our missiles, bombs and torpedoes being American. On our ships using American turbines. On our upcoming destroyers having American radars, etc.
We're also at a point where we don't have the luxury of time because the Hornet fleet is on the verge of falling out of the sky. So whatever public opinion is, we'll be buying F-35s. The only question is the number.
The original Conservative number was 65 frames to meet NATO and NORAD commitments. The Liberals got caught in a lie trying to justify their Super Hornet sole source. To cover it up, they said the force needed to be 88 frames. We could go back to 65 frames.
But cutting this order, only has leverage value if we actually spend more on jets elsewhere. It's not leverage if we just cut the number of planes. At that point, the Americans will (and not without justification) start talking about how we're not protecting Canadian airspace. If you want to give Donald Trump an excuse to have the USAF patrolling Canadian airspace.....
