Moscow is playing it cool because it may choose among a staggering array of counterpunches. It enjoys the support of the BRICS group of emerging powers, the non-aligned movement (NAM) and the Shanghai Cooperation Organization (SCO). Composing with the US, Moscow agreed to impose sanctions on Iran, and is a key player in the P5+1 nuclear negotiations. If the sanction comedy goes on, Moscow has already announced it will play hardball with the P5+1, will cease to sanction Iran, and may even, finally, weaponize Tehran with jewels of the S-400 variety.
Moscow -- the number one oil and gas exporter on the planet -- can also play further hardball with Europe's dependency on Gazprom; clinically target US companies working in Russia; speed up the BRICS-coordinated escape from the US dollar, as in a new international payment system in a basket of currencies for the BRICS as well as other emerging markets; and even activate the ultimate economic nuclear bomb -- which is to accept payment for Russian oil and gas in ruble, yuan, euros or gold, thus delivering a terminal blow to the petrodollar.
And that, ladies and gentlemen, will be the end of the comedy hour.
