That said, the F-35 is not designed to be a visual dogfighter. It has dogfighting capabilities, but its main design principle is high situational awareness enabling kills from far away - seeing the enemy from long before it itself is seen.
That's fine - but the only issue there is what rules of engagement will it be forced to operate under? It's a little hard to maintain a bvr fight when you are forced to visually id someone. In today progressing world of stealth I also question that it will not later face opponents that can get in close before they are themselves detected.

We're talking about carriers here, right? How many of those do you think the Russians can run through the Artic, let alone most of the other places you mentioned, in the winter?
Spoken like a real self-obsessed, greed worshipping USian.
You probably consider yourself very enlightened and open minded.
