You all underestimate Russian threat.
Someone's playing too much "Command & Conquer" ...
The Americans are smart enough to prevent the tsunami by freeing Peter Madsen from a Danish prison with a Navy Seal 7 team, smuggling him onto the Russian nuclear robotic submarine and letting him kill the whole Russian crew there, before they can set off the nuclear explosion that is wiping out the East Coast.
They then bring the submarine and the dead Russian crew members to the US, hand Madsen over to the Danes again (but only after the above-mentioned Navy Seal 7 team has also deployed Peter Madsen to the Kremlin in a secret night operation, where he sneaks into Putin's bedroom, has gay sex with him and then rapes, kills and dismembers him) and then use the Russian technology to build their own nuclear tsunami weapon that will wipe out St. Petersburg (not the FL one) first and then Moscow gets destroyed with the MAGA-bomb.
