My point was that there is/was a deal with Finland and Canada signed by the Biden administration regarding the development of icebreakers.

Not that there will be a new deal...

Any deal with Trump is not reliable. Trump is even criticising his own 2018/2019 USMCA deal with Canada and Mexico, claiming it favours Canada and Mexico and that is was a mistake by previous administrations (ignoring that it would have been his own mistake).
