Would like to see more about the arctic routes, that seems interesting and plausible.
But I find the "Second Suez Canal" theory less convincing. If they try conventional methods (or worse, hire the Boring Company) to build that it'll take way too long until it's done. And the nuclear bomb method would draw too much opposition even from "israelis".
Besides that, any canal in that region would be really hard to maintain given all the possibly opposition put up by the countries in the region, and it'd still be vulnerable to Anserallah attacks off the coast of Yemen.
I think the US benefits way more from having that whole canal closed (blocking Mediterranean trade with the East) than controlling it, and "buying" Gaza would be a stepping stone towards that.
