Did you intentionally screw up the dates in that quote pyramid LW? lol.
I just put random numbers in because I can't get the original quotes (old thread locked)
Global Warming is making it somewhat moot, but we could still end up in a situation where we find out we need them* and wonder why the hell we don't. Also, that one icebreaker is going to take what, five years to build.
If global warming reaches a point where the USA doesn't need icebreakers then we'll be beyond fucked. Like "we need to get off the planet now" levels of fucked
I also read somewhere that Russia is naturally an Arctic power since so much of their coastline is that, while they aren't such a great open-ocean (Pacific and Atlantic) power while the US is the reverse. That's just what happens when specialization occurs.
Geographical determinists pointlessly ignore how leaders, circumstance and national institutions dictate policy & capability, the US could be an arctic power but their leaders do not believe that the arctic is traversible, in spite of observable evidence to the contrary of Russians planting their flags in the ice and transporting cargo to and fro.
There is nothing natural about the USA being a blue water navy, any more than it is natural that Brazil is not. There is nothing natural about the UK being a blue water navy, "but muh islands, muh natural island sea powers," contrast with how Madagascar and New Zealand do not possess such navies whilst land powers like Imperial Germany could conjure up potent navies ex nihilo despite being land powers.
Specialization also does not pose a hard constraint for a country like the USA, which does not lack for countries which can train in areas of specialty the USA wishes to develop. There's an amusing anecdote of US marines training Japanese marines, losing their own marine capabilities to budget cuts, and then receiving training from Japanese marines after the US marines were expanded again. In the case of arctic specialization, you got Canada, UK, Norway (maybe Sweden depending on whether they're Finlandised yet) to pick from
*We could do what we did back in WWII to quickly produce ships, but still....
Trump declaring a state of emergency to build icebreakers instead of a wall would be a welcome diversion
