Check out the following definition of economic terrorism:

“Contrary to “economic warfare” which is undertaken by states against other states, “economic terrorism” would be undertaken by transnational or non-state actors. This could entail varied, coordinated and sophisticated or massive destabilizing actions in order to disrupt the economic and financial stability of a state, a group of states or a society (such as market oriented western societies) for ideological or religious motives.

These actions, if undertaken, may be violent or not. They could have either immediate effects or carry psychological effects which in turn have economic consequences.”[1]

Given that Government Sachs has been involved in the destabilization of numerous western economies (most recently Greece), the above definition almost perfectly describes GS.
