So, knock down the wall, get the West to turn its swords into ploughshares, and then pour billions into redeveloping the Soviet economy and natural energy resources, then turn off the tap, kick out the decedent bourgeois, watch with scadenfreude as the West's budget forces are defeated by well funded ragheads, then put the wall back up.
Kick the West's butt in Cold War II.
Could be the greatest confidence trick in history.
