US troops in Europe and the Middle East are there to provoke China more than Russia or Iran
NATO’s recent land and sea exercises in eastern and southern Europe as well as the Black Sea frontiers of Eurasia are at face value, provocations designed to anger and intimidate Russia. Likewise, America’s presence in Iraq and Syria are at face value, provocations designed to angry and intimidate Iran. But they are also something else: they are provocations designed to anger and intimidate China.
The key element here lies in understanding the geography of China’s massive trade/commerce project, One Belt–One Road, also referred to as the New Silk Road.
