With all this concern over Iran building a nuclear weapon we should stop to see if Iran has any concerns. It seems they are a bit concerned about the United States building yet another nuclear weapon:
TEHRAN—Amidst mounting geopolitical tensions, Iranian officials said Wednesday they were increasingly concerned about the United States of America’s uranium-enrichment program, fearing the Western nation may soon be capable of producing its 8,500th nuclear weapon. “Our intelligence estimates indicate that, if it is allowed to progress with its aggressive nuclear program, the United States may soon possess its 8,500th atomic weapon capable of reaching Iran,” said Iranian foreign minister Ali Akbar Salehi, adding that Americans have the fuel, the facilities, and “everything they need” to manufacture even more weapons-grade fissile material.
