LO, you may be able to add Australia to that list, we did plan for 100. We have committed to about 75. We replaced the F-111 with 24 FA-18f till a 2025 time frame. The now 36 super hornet/growlers fleet may well extend and be retired with the USN fleet.
Canada I see as politics, as both parties have shown support for the F-35. It must be a well governed country if the way it is procured is all they have to squabble about.
They will be 'publicly' selling the F-35 for the next 30 years with carefully chosen phrases. I don't think that sways the numerous evaluation teams that report to their air force leaders and governments.
