The USA should acknowledge the Cold War is back on and form a NATO-like pact with Eastern European countries such as Poland, including military bases and nuclear armaments. We also should loudly declare Bosnia an imprisoned state calling for them to revolute if not allowed to vote to withdraw from Russian domination and all other regions of Russia to do the same. We should do the same for all regions on and within Russia's Southern border.
In that, Russia is outnumbered and with chaos on and within two of its borders. Russia no longer has the size, population or economic base it had as the USSR. Russia could not withstand the contest. The number of intense enemies by the tens of millions Russia has within and on their borders would overwhelm Russia and would push Russia into a monor and only regional power.
