Nor can the resistance rely on external support as it used to when the West, South-East Asia and China united to oppose the Vietnamese occupation of Cambodia.

The current three-day surge is the strongest for the major averages in three months, but with resistance looming the potential for an external factor to spark another downturn (like, say, the Fed ending its QE2 program Thursday) is certainly important to keep in mind.
