This thread was inspired by @fresh_42 's comment in another thread. Making a new thread as what I want to say in response is really OT for the thread where initial comment was made.
To this American, the US GDP dollars involved are of little relative significance in what you describe. I do agree with you that the US defense industry is likely to lose market share.
I hope that in 10 years one can compare the rise of Western European modern weapons suppliers to the rise of Airbus. Boeing would probably be a bigger company today if Airbus didn't exist, and the world is better for having both Airbus and Boeing.
This comparison I'm drawing is completely off-the-cuff, so maybe its naive or simplistic. My gut feeling is that the world is better off with Europe being able to develop and source their own modern weapons systems.
I expect this trend, if it happens, shrinks the market for US made military hardware. Imagine what the world is like, though, if the most effective military drones are developed and sourced from Italy or France or Germany, and they are seen as the "F-16" of the times, and the US needs the goodwill of whatever country sources them to maintain parity.
As the world shifts away from high-cost / low-volume hardware dominating a battlefield, the barrier to entry becomes much lower anyway, so maybe even without Trump this trend would be happening?
Other sources reported that 70 cents of each dollar spent was going to the US, and Canada will shift these expenses to its home market and Europe. E.g., they said that Canada will look for French, German, and Spanish companies to renew its fleet of submarines.
