wow.
i've written here a bit about turkey having difficulty finding a greater trade bloc to work with - rejected by racist europeans and racist arabs alike, with impossible historical tensions to the north and east.....and hundreds of kilometres from "home" in central asia....
if turkey is shifting to the sco, this is a major blow to us/nato hegemony in the region.
