US President Donald Trump said that his country would move next week to activate a clause in the nuclear agreement concluded with Iran allowing the re-imposition of sanctions on it, and he also ruled out his participation in a summit proposed by his Russian counterpart on Iran.

"We will resort to the snapback," the mechanism that any state party to the nuclear agreement concluded with Iran in 2015 can resort to, to re-impose sanctions on it, Trump said during a press conference at his golf resort in Bedminster, New Jersey.

However, the possibility of the United States activating this mechanism raises controversy since Washington withdrew from the agreement by a decision of Trump himself.

On the other hand, Trump has ruled out his participation in a summit proposed by his Russian counterpart Vladimir Putin on Iran, stressing that he prefers to wait until after the US presidential elections.

On Friday, Putin called for an emergency video summit that includes the leaders of the 5 + 1 group (the five permanent members of the Security Council and Germany) and Iran, to resolve the prevailing differences in the UN Security Council over the Iranian nuclear file and ways to contain tension in the Gulf.

Commenting on these developments, US Secretary of State Mike Pompeo said on Saturday that failure to extend the arms embargo on Iran is a grave mistake.

Pompeo added - in a press conference during a visit to Poland - that it is "a serious mistake ... we regret that."

On the other hand, Democratic Senator Chris Murphy said that the failure of the US draft resolution to extend the arms embargo on Iran in the Security Council constituted a devastating defeat.

Murphy added in a tweet on Twitter that of the 15 members of the Security Council, only the Dominican Republic voted with Washington, and thus America has become amazingly weak, and so also the rest of the world views Trump's disastrous strategy towards Iran.

It wasn't a defeat. It was a rout.

Of the 15 Security Council members, only the Dominican Republic voted with us.

This is how stunningly weak America has become, and how disastrous Trump's Iran strategy is viewed by the rest of the world. https://t.co/5oDgqQ7PlU

In a second tweet, Murphy said that the embarrassing failure of the arms embargo decision on Iran constitutes a warning of the dangers of placing people without diplomatic experience - such as US representative Kelly Craft - in the most important international positions.


For its part, an American "failure" , Tehran considered this refusal to confirm the isolation of the Trump administration, and Iranian President Hassan Rouhani said that the failure of the United States to pass a resolution against Iran in the Security Council is a historic and humiliating loss for Washington, considering that this step shows the strength of the nuclear agreement that He was able to stand in front of the American administration and bear it with defeat.

Rouhani added that countries did not vote on this resolution, because they realize that preserving the nuclear agreement is important and necessary to ensure the security of the region and the world.

In a vote by the United Nations Security Council on the US endeavor on Friday, China and Russia rejected the proposal, and 11 countries, including France, Germany and Britain, abstained, and only the United States and the Dominican Republic supported the extension of the embargo.

"For the first time, the United States submits a draft resolution to the Security Council, and it only gets the support of one country, which is a small island," Rouhani said in a televised speech.

"With the failure of the American draft resolution against Iran in the Security Council, the Islamic Republic of Iran will have achieved another great success," he added.

The arms embargo imposed on Iran is scheduled to end next October under the 2015 nuclear agreement between Iran and world powers, which lifted many of the international sanctions imposed on Tehran in exchange for imposing restrictions on its nuclear program, and the United States withdrew from the agreement in 2018.

Tensions have escalated over the Iranian file since US President Donald Trump decided in 2018 to withdraw his country from the nuclear agreement concluded between Tehran and the major powers that froze the Iranian nuclear program and re-impose stifling economic sanctions on the Islamic Republic.
