Canada

F-35 is the most advanced aircraft currently available. We've also already sunk enough money into the program to pay for the first 16 IIRC. This puts us in an awkward position, considering the possibility of degraded functionality of the F-35 without US assistance^1^.

One of the worst ways to balloon military spending without getting anything in return is to keep changing your mind and hanging procurement up in endless indecision. Combined with the money already spent, I think we have to stick with F-35 for at least a bit.

I like the Gripen, and I'd suggest a switching some of our 88 fighters to Gripen's, but apparently Gripen's aren't that much cheaper.

Long term though, I think Canada should get in on GCAP, the Global Combat Air Program. It's not expected to deliver until 2035 if everything sticks to plan, so we'd still need the F-35 or Gripens I was mentioning in the interim.

^1^ My understanding is that the "kill-switch" myth is pretty much that, a myth. There are software systems that depend on the US, apparently ALIS/ODIN, plus the MDF file updates. The possibility of a kill-switch can't be totally excluded IMO though, there is a lot of software in the F-35, and the US writes and patches it all. Even if there isn't a kill-switch, the US knows what vulnerabilities they are patching, and if any of them where exploitable, I'd imagine they'd know.
