article says Musk's technology could built the tunnel for a mere $8 billion. We've been wasting multiples of that for years. But the article does not mention the necessary cost of building a yuge Alaskan military base and encampment of missiles pointed at Russia to go along with the actual tunnel.
No need for a huge base or missiles you can cave a tunnel in with a truck load of shaped charges. The idea of sending an invasion force underwater into a choke point with only one entrance and one exit is insane.only people with zero military experience even suggest such idiocy. Punch a hole anywhere along its length below the water table and the sea floods in killing everyone in it fast too a literal wall of water like a hammer crushing everything in its path. Each side could , and would set up demolition charges near their entrance portals below said seawater level. At the first hint of war those would be blown and it would be years if ever before the tunnel could be pumped dry and then repaired.seawater would absolutely wreak the rails and tunnel infrastructure. Look at what Super storm Sandy did to the tunnels under the Hudson and East river’s billions to repair what seawater did when they flooded. Not an easy fix or fast. So no the Russians nor the Chinese are invading via a tunnel. As for spec ops they would come via submarine or aircraft with civilian transponders or even on civilian jets and just jump from altitude all spec ops train for HALO and HAHO jumps the 727 was specifically modified with a vane that above 100knts the airflow pushed this vane back and it physically prevented the rear stairs ramp from opening in flight after DB Cooper’s jump. There were “special” 727 that had that vane removed for various alphabet guys to use. The Russians fly Yak42 it doesn’t have the no open vane and does have rear stairs ramp you could jump at altitude from one with ease. Then again the commies just send university students of fighting age by the hundreds of thousands per year so why jump at all. The spec ops teams and sleeper agents are already here.
