From Israel to Lebanon to Iraq, the Islamic Republic of Iran has been fomenting war (see here for more on this) in a bid to intimidate the US and other nations against taking a tougher line on its nuclear enrichment activities:
TIKRIT, Iraq -- The U.S. ambassador to Iraq accused Iran on Tuesday of having forces in Iraq and said Tehran could use the war between Hizbollah militants and Israel in Lebanon to try and further destabilize the country. "The region is very much interconnected. What happened in Lebanon affects things here," Zalmay Khalilzad told reporters. "Iran ... has some forces here. There is the possibility that they might encourage those forces to create increased instability here."
Imagine how the regime will act if it acquires nuclear weapons. Speaking of, on August 22, Tehran is supposed to give its answer to the latest nuclear deal on the table. Look for the regime to play for more time by offering some sort of conditional acceptance of the deal. It will be just enough for Russia and China to argue that the consideration of sanctions at this juncture would be counterproductive.
