Canada

Big pipeline projects require a guaranteed climate terrorist future with world subjugated to dead ender energy for 40 years. Oil use, other than for war, is significantly down in last 2 years. EVs are making a big dent in China and Europe, and South. Desperation to steal public funds to subsidize oil industry was part of funding for Trump's victory, as a last gasp for industry profit protection.

If Alberta wants to pay for a pipeline east, rest of Canada can be nice about it. Smartest move would be expanded railways through Ontario and Quebec that go a bit norther than existing routes so that more cargo volume can pass through Canada, and be remote enough that accidents don't kill too many. In a greener future, population around those rail corridors can increase, even as oil use dies off completely, or sufficiently to not have large export markets, that makes oil only infrastructure a bad investment. But even if using existing railways/trucks causes more deaths from accidents, it's still the smartest/least economic risky path.

Absolutely not under any circumstances, should Federal government submit to Alberta referendum extortion as a reason to invest 1 red cent into Alberta. I'd rather see export tariffs on Alberta oil, with 50% of the revenue set aside to repay Alberta after they set a path towards Canadian unity. I'd rather see very aggressive demands on secessionist movements to allow subregions to vote to either become independent city states or Canadian associated regions.
