"And then the two global threats [from Iran], of course, are their nuclear aspirations… and then cyber is the other global threat they pose," Dempsey stated at a US Senate Foreign Relations Committee hearing on the US President Barack Obama’s request for authorization of use for military force (AUMF) against the Islamic State.
Dempsey also said Tehran's regional surrogates and proxies, weapons trafficking, ballistic missile technologies and new mines constitute security threats.
The United States together with Russia, China, the United Kingdom, France, and Germany, better known as the P5+1 group of countries, are conducting talks with Iran to ensure the peaceful nature of that country’s nuclear program. The negotiators have set the preliminary nuclear deal for the end of the March. A deadline for concluding a long-term comprehensive nuclear deal has been set for July, 2015.
