Step 1,roofie the entire population of Russia Step 2,build a dam 200 feet in the air. The deepest part of the Gulf of Finland is 125 ft deep. Step 3,we convince the world's elite to build said dam quickly,we can lure them with submarines to the Titanic and maybe chicken teddies Step 4,build 8 track long railway between Estonia and Finland,along with a 4 lane highway for easier transport of goods and people Step 5,the Russians will be waking up soon so we don't have much time. Put a bunch of nuclear weapons in the gulf and the heat will flash boil the gulf,turning it into a salt flat

If Russia destroys the dam,there'd be a 125 ft tsunami crashing into St.Petersburg,and Article 5 would be triggered. This plan can't go tits up
