Purposeful organization of Ponsi schemes my the KGB on the American free market (causing speculation bubbles).
Massive forgery of US currency and its distribution worldwide (increasing inflation).
Support of large US businesses in subverting competition to create monopolies on the US market (and subsequently, market failures).
Constant smear campaigns regarding the practices of US enterprizes in regard to OSH and enviromental hazards to lower their competitiveness.
Theft of patents and infringment on other intellectual property rights, providing them to competition.
Buyouts of energy sector enterprizes (powerplants and power grids) only for the purpose of shutting them down.
Theses are just a few thoughts.
