Former Mossad chief Efraim Halevy on Sunday called on the West to have a dialogue with Iran amid denials of reported talks between the US and Tehran over the Islamic Republic's nuclear program.
“I realized that dialogue with an enemy is essential. There is nothing to lose," Halevy said in an interview with US website Al Monitor.
"The claim was, if you talk to them, you legitimize them. But by not talking to them, you don't delegitimate them," he added.
