As Iran continues to say it is developing nuclear enrichment for power supply and not weaponry. This has caused great tension for the United States, which perceives Iran acquiring such weaponry a threat to the stability of the world. Yet of recently there is a similar sanction as one in Saddam's Iraq in Iran. This is once again causing varying degree of pressure on Iran. yet, it does seem that Iran wants to negotiate with America.
"The countries(Iran and US)were meeting in Istanbul in an attempt to find common ground at talks jeopardized by Tehran's refusal to discuss demands that it curb nuclear activities that could manufacture the fissile core of nuclear warheads(haaertz.com)."
As you can see there are talks between Iran and western powers to negotiate.
