Even defenders of the deal former President Barack Obama’s administration negotiated with Iran admitted that it would delay Tehran’s acquisition of nuclear weapons only about 10 years.

That was three years ago.

Now, some are warning that President Donald Trump’s decision to pull the United States out of the pact with Iran may spell disaster.

Iran was one of the primary topics of Trump’s speech this week at the United Nations. He called for the U.N. General Assembly to join this country in putting pressure on Tehran’s hardline leaders to abandon development of nuclear weapons and stop attempts to destabilize several Middle East nations.

Prior to the speech, German Foreign Minister Heiko Mass told reporters his country, along with Russia, China, Great Britain and France, will try to keep the 2015 deal alive.

Mass warned that under pressure from the United States, “Iran might one day resume military nuclear” development. “We don’t want this because it would set the entire region ablaze,” he added.

Yet Iran has spent billions of dollars – some of it provided by this country under terms of the 2015 pact – in attempts to set the region ablaze. Tehran’s activities include support of terrorist groups.

And Iran never really stopped work to develop nuclear weapons. In an interview this month, an official of the country’s Atomic Energy Organization admitted that.

“We are at a considerably more advanced status than when we signed the deal. The country is moving ahead in nuclear activities at a favorable pace,” commented Behrouz Kamalvandi.

Trump is right. The only means of preventing Iran from obtaining nuclear weapons is for other nations to join the United States in putting economic pressure on the regime.
