The US media are again reporting signals that Iran is open to diplomacy for a deal to end its nuclear standoff with the West, just one day after they cited 2013 as the year of decision. According to the New York Times of Friday, Iran has slowed down uranium enrichment and this, according to one American official, amounts to putting “more time on the clock to solve this.” DEBKAfile: None of the umpteen diplomatic bouts over the years has ever caused Iran to yield an iota on its nuclear program but were used on the contrary to chalk up progress.  According to ABC TV, an Iranian official says the controversial military site [at Parchin] may be opened to UN inspection “if foreign threats weaken.” DEBKAfile: Tehran has been toying with the nuclear agency on Parchin for two years.
