"Why do almost all countries support restoration of #JCPOA? Because it is a key element of the int. non-proliferation architecture. The deal, if restored, can provide credible assurances of peaceful character of the Iranian nuclear program via intrusive #IAEA verification," Ulyanov tweeted.
"Some people oppose #JCPOA restoration. But Is there a realistic alternative? No. Maximum pressure policy totally failed and just prompted development of the Iranian nuclear programme beyond 2015 parameters. This is a matter of fact. Does anybody want this trend to continue?" he asked.
Iran has repeatedly assured of the peaceful nature of its nuclear activities.
