Playing for Keeps,
Let me insert at the outset, that there is global brinksmanship, with the threat of nuclear holocaust.
US global hegemony must control the energy flow to European industry and society to retain Europeans as vassals.
Without that, the $US will not retain global reserve currency status, which allows vassal states to produce goods for export to the US, and accept US promises for them. That is the mechanism of tribute-extraction.
The US is in a very good position to become a global citizen, even a "first among equals", if the costs of global hegemony can be shed.
WW-3 will destroy what humans have created, at a time in history where all of the easy resources have been spent, and the planet is heating up from it.
Neocons at the reins of empire, who have their own bunkers somewhere, may really not be rational actors. We'll see, I guess.
Them's Fightin' Words!
In a statement, the US "intelligence community" said that it is “confident” that the Russian government “directed the recent compromises of emails from US persons and institutions, including from US political organizations”
The US added that “these thefts and disclosures are intended to interfere with the US election process”.
Russia does not have the vast array of forces, which the US/NATO command, so a head to head confrontation would be rapidly forced up the escalation-tree to nuclear holocaust, which Russia has historically avoided. Russia does have specific technical advantages in some weapons systems, and specific advantages, on the ground in Syria and Ukraine, for instance, which the US/NATO can't realistically defeat without open commitment of forces and heavy losses, and possibly with overt failure, as well.
Tom sends this article, which looks at Russian options for asymmetrical responses to western forces, which deny opportunity, and inflict high costs if action is taken. (Are all players rational? Playing-crazy is a form of brinksmanship, which Richard Nixon played, and Israel plays routinely.)
