Russia will be an economic wasteland in a short time. The best way to stop the Russian war machine is to make it unaffordable.

Many (most of the big ones) shipping lines are now refusing to take or receive containers to Russian ports, which is effectively a "Blockade" by any standard. Pretty much all Western businesses with interests in Russia are either suspending, divesting or shutting them down. Their banks have been frozen out of the SWIFT system.

People can't get cash out of ATMs, the banks are running out of dollars as people try to offload the ruble.

This could go one of many ways, but it either pushes the country to the verge of revolution, or deposing Putin in another way or it backs him further into a corner, further pressure on an unhinged mind that dreams of empire but sees defeat and that could be very dangerous, for everyone.
