Ambassador Joseph reiterated, “We must change course dramatically, we must recognize that the regime will not moderate, we must pressure the regime from every possible direction, we must deny it access to the international financial system, we must stop the serial concessions in the economic field, we must respond to Iranian adventurism in Syria, … and the most importantly we must support the Iranian Resistance to this regime. That is, I think, probably the most important thing that we can do. We cannot have regime change from outside, it has to come from the inside but we can certainly support that.”
