Need to Avoid Drastic Response to US Nuclear Move

The US decision to tighten restrictions on Iran's nuclear activities is meant to prompt the country to take "drastic" measures, but officials should stay vigilant and increase their bargaining power only through legal means, a senior lawmaker said. 
"The new nuclear sanctions are aimed at compelling Iran to end its membership in the International Atomic Energy Agency and leave the nuclear Non-Proliferation Treaty so that it could be brought back under Chapter VII of the United Nations Charter, but we should not take any drastic measure," Heshmatollah Falahatpisheh told ISNA in a recent interview.
Chapter VII authorizes UN-mandated external action against a country.
