Iran's response to Israel's provocations should be non-violent and measured.

Iran says it could quit the global nuclear Non-Proliferation Treaty (NPT) if European countries refer it to the UN Security Council over a nuclear agreement, a move that would overturn diplomacy in its confrontation with the West.

Britain, France and Germany formally accuse Iran of violating the terms of its 2015 agreement to curb its nuclear program, which eventually could lead to the reimposing of UN sanctions lifted under the deal.

Iranian President Hassan Rouhani reiterates on Sunday that Tehran would remain committed to its 2015 nuclear deal if its interests can be protected and says the US withdrawal from the accord is a "violation of morals".

President Donald Trump has railed against a deal to curb Iran's nuclear program, but officials say that far from scrapping it, he is considering kicking the decision to Congress.

Iran says that it has successfully tested a new medium-range missile in defiance of warnings from Washington that it is ready to ditch a landmark nuclear deal over the issue.

Iran can abandon its nuclear agreement with world powers "within hours" if the United States imposes any more new sanctions, Iranian President Hassan Rouhani says.

US imposes fresh sanctions on Iranian companies and individuals over a recent ballistic missile test.

Iran "has opened a new chapter" in its ties with the world, President Hassan Rouhani has said, hours after economic sanctions on Tehran were lifted.

Prime Minister Sheikh Hasina extends her full support to Iran's nuclear deal with big powers and expresses her firm hope that it would pave the ways for Iran's economic cooperation with international community including Bangladesh.

Seeking to sell his nuclear deal with Iran to a skeptical Israeli public, President Barack Obama has repeatedly declared his deep affection for the Jewish state. But the feelings do not appear to be mutual.

Post World War II power balance between Zionist Israel and Arab-Persian Muslim countries, who considered Israel as a “pushed in state” in Middle East, is now being replaced in the post-Iran treaty era by an emerging strategic balance between Iran on one side, and Israel plus Gulf Arab countries on the other side.

Critics of the upcoming accord have pointed out that Iran will not play by the rules and may continue a covert programme for uranium enrichment outside designated nuclear facilities covered under the agreement.

From the Iranian perspective, optimists see Iran's gains in a number of ways. The ailing economy of Iran which was caused by western sanctions will now get a chance to improve.

The Obama Administration, which defied the hawkish opposition at home and abroad and signed the historic Nuclear Deal with Iran, seems to have condoned President Erdogan's military operation in Iraq.

Bridging the gap between Iran and the West would help soften Iran's present voice against Israel through a possible political and social transformation in favour of the West.

The only thing to lament about the agreement reached by Iran and the P5+1 (the UN Security Council's five permanent members – China, Britain, France, Russia, and the United States – plus Germany) in Vienna this month is that it was not signed and sealed a decade ago.

The US Congress has 60 days to review the agreement. During that time, President Obama cannot lift the sanctions.

Rouhani and his allies are unable to offer ordinary Iranians economic hope – a failure that causes them to lose both the legislative and presidential elections.

After the marathon 18-day Vienna talks a historic deal was signed on Tuesday between Iran and six global powers -- the US, Russia, China, Britain, France and Germany.
