RE:Bombardier will not pay 25% Tarrifs You're right.
The odds are not on the side of tariff for a company like Bombardier.
It could be struck with tariff only if they apply wall to wall tariff on all goods. A way to bring US inflation back to the height they had last year with the higher interest rates that come with; not a brillant move.
If they choose for selected targets, as you said, strucking business jets could be ineffective.
Odds are on our side.
