I haven’t done adequate due diligence yet - could be inaccurate
I came across this article alleging that Germany is considering bailing on the F-35 aircraft because the US can remotely disable them.
If the US could do this to German F-35s, presumably they can do it to ours…
Additional reporting alleging concern in Canadian defence circles
Honestly, it mostly just sounds like more fear mongering about the F-35, which has been going on for ages, and is mostly a Russian disinformation campaign. Pierre Sprey - the originator of all the F-35 criticisms that routinely get handed around - is very regularly a paid guest on RT and other Russian state controlled news outlets.
Basically Russia is really scared of the F-35 program and would much rather their enemies keep flying upgraded fourth gen fighters. If the US was selling the F-22 to the rest of the world you’d be hearing all the same noise but about that plane instead.
