The Russia/Ukraine and NATO question cannot be overlooked as motivation for this den of thieves. Recall that a pack of Harvard reformers opened up Russia for massive looting when they swooped in during the Yeltsin era to buy up shares of Russian assets that were distributed wholesale to the population. The US ex-patriot swindler Bill Browder (now British subject) whom John McCain championed with the phony Magnitsky Act that Obama signed into law was part of this apparatus. This carpet-bagging swindle continued in Ukraine with billions being carried out by Democratic operative's families like Pelosi, Biden, Kerry, et al.
The overlying issue is the debt bomb that was created by the derivative securities of these same Harvard "quants." Since 2008 the Bernanke helicopter bailouts has created an even larger bubble that will inevitably blow. When that happens either the out of control speculative financiers that created this mess will lose their power through bankruptcy via return to Glass-Steagall and the US will arrange for new trade agreements with the BRICS nations or these loonies will provoke WWIII.
This is why they fear more than anything about an out of control Trump. For what he might do in a financial geopolitical crisis.
