I like the spirit of this thread - although it's trickier than I expected to share an opinion on the next POTUS's influence on the CAF without also at least partially sharing one's opinion on the POTUS himself!
I think it's safe to say that if Trump does become President again, it wouldn't affect our timelines or budgets in a negative way...
Even if our baseline budget doesn't increase, there will undoubtedly be an expectation to provide some core capabilities in support of NORAD & NATO - and that expectation could be quite beneficial in getting certain things online sooner/faster than turn glacial pace Canadian procurement seems to run at...
The bigger picture reality, in my opinion, is that Canada as a whole is represented by leaders who are far too stupid to recognize the potential opportunities that are before us, or could be before us, as a country.
Having Trudeau making insulting and misleading comments about Trump (done recently) isn't going to help our position at all when it comes to trade or negotiating economic opportunities.
With our current leadership, I don't see any widespread economic growth coming anytime soon. Without a major shift in our intention as a country & the corresponding economic policies that actually support economic growth, we won't/can't be investing a whole lot more in the CAF regardless of who is POTUS.
(Finding efficiencies in procurement, rolling out of new kit, recruiting & training efficiencies, as well as making smarter investments in military housing could help us get more bang for our buck & help us produce a better product while not requiring a budget increase)
