the F-35 is only supposed to be sold to close allies anyway so I doubt secrecy from the US is on the top of buyers' minds? conversely, they'd likely engage in joint exercises with the US.
The US already in an economic dispute with many allies (including Canada) citing national security threats. At this rate, the US might have no close allies left by the end of life of the F35s.
POTUS needs to cite national security as is how he is able to unilaterally place those tariffs without congress. Furthermore natsec threats doesn't mean that a partner is not trustworthy. Australia is one of America's longest standing and most dependable ally. If the US were to use Australia as it's primary rare earth mineral supplier a perfectly valid argument could be made that in the event of a global war an adversary could disrupt trade between the US and Australia. Thus there would be a national security threat.
He has access to more intelligence then you and I. He must legitimately feel Canada is a threat to our security. Possibly even imminent invasion, or hostile action. He has the intelligence.
Someone who will persist in a racist lie of birtherism conspiracy nonsense for five years, has zero credibility. What this person "legitimately feels" is so totally out of scope because first his assertions of fact are frequently provably not reality based, second there is no ability to assess anyone's feelings. Why must he legitimately feel Canada is a threat? Why can't he be lying about it just to get what he wants, whatever that is?
This is short term thinking. Allies are aware the administration of the United States can change every 4 or 8 years. If what you need are big guns, the United States is still the best game in town.
Our allies have historically been comfortable that the US President would be fairly responsible with shared intelligence, regardless of which party's in control.
It's slow, but interest rates are going in one direction in the whole world. The last time they were so low was the time before the currencies were hyperinflated and WWII started.
