When you Democrats said "build bridges, not walls" you were not kidding. Tell me, which country is on the other side of the Bering strait?
We still do business with Russia. For latest, look at Trump's buddies aluminum sanction withdrawal. 34 mi The Bering Strait is about 82 kilometres (51 mi) wide at its narrowest point, The Diomede Islands are often mentioned as likely intermediate stops for the hypothetical bridge or tunnel (Bering Strait crossing) spanning the Bering Strait.[4] Suggestions have been made to construct a Bering Strait bridge between Alaska and Siberia. However, despite the unprecedented engineering, political, and financial challenges, Russia green-lighted the US $65-billion TKM-World Link tunnel project in August 2011. If completed, the 103 km (64 mile) project would have been the world's longest.[18] China considered construction of a "China-Russia-Canada-America" railroad line that would include construction of a 200 km (120 mi) long underwater tunnel that would cross the Bering Strait.[19]
LOL, so all of our international travel will hinge on Russia being the gateway to the world? GTFOH! I'd still like to hear how China is going to fall in line with this Green New Deal right after Russia agrees to being an international conduit with rail tracks zig-zagging across Siberia and the rest of Russia lol. Yeah, I can totally see Russia allowing this to happen LOL. BTW... Argentina to the UK is going to be one heck of a Journey lol.
I'm not addressing ending air travel; just the idiotic notion that the world can't be linked by railroad through the ocean.
All of these high speed rail plans ignore the carbon footprint of the equipment involved to make the tracks and build the railways. https://www.citylab.com/transportation/2011/11/how-green-high-speed-rail/492/
The true idiotic notions are laid out in Alexandria Ocasio-Cortez's "Green New Deal". I am still waiting to hear how and why China is not Priority #1 for addressing climate change? China emits more carbon dioxide than the USA and EU combined. Why is that not Priority #1? How will China be stopped?
