President Obama used his weekly video address to defend the Iran nuclear deal against critics he said are using "overheated and often dishonest arguments" to attack the agreement.

"The deal will make America and the world safer and more secure," he said. "Still, you're going to hear a lot of overheated and often dishonest arguments about it in the weeks ahead."

Trying to get ahead of those arguments, Obama laid out his defense, first taking on the assertion that the deal "somehow" makes it easier for Iran to obtain a nuclear weapon.

The deal, he said, "actually closes off Iran's path to a nuclear weapon." While Iran now has enough nuclear material to produce up to 10 nuclear weapons, he said the deal will force them to ship 98 percent of that material out of the country, "leaving them with a fraction of what it takes to make even one weapons."

He also noted that the deal forces Tehran to "repurpose" two key nuclear facilities so they can't produce materials that could be used for a nuclear weapon.

When it comes to the argument that Iran will inevitably cheat, Obama fell back on his contention that the deal will have "unprecedented 24/7 monitoring of Iran's key nuclear facilities.

He did not, however, address the access delays inspectors will face if they discover a suspicious site not on the approved list that they want to look over. In that case, Iran would have more than three weeks – 24 days – to dispute the request and prevent inspectors onto the site.

If Americans hear the argument that Iran faces no consequences if it violates the deal, the president said they should regard it as "patently false."

"If Iran violates this deal, the sanctions we imposed that have helped cripple the Iranian economy – the sanctions that helped make this deal possible – would snap back into place promptly," he said.

Critics, however, have argued that international businesses, as well as Russia and China, are eager to engage with Iran and the sanctions will be difficult or nearly impossible to rebuild once they are stripped away.

While acknowledging that the deal doesn't resolve all threats Iran poses to its neighbors and the world, he said it does more than "anyone has done before" to make sure Tehran does not obtain a nuclear weapon.

"That's why it's in everyone's best interest to make sure this deal holds," he said. "Because without this deal, there would be no limits on Iran's nuclear program. There would be no inspections."

"The sanctions we rallied the world to impose would unravel," he continued. "Iran could move closer to a nuclear weapon. Other countries in the region would do the same. And we'd risk another war in the most volatile region in the world."

Republicans this week chose not to point out the problems with the Iran deal in their weekly video address , turning instead to the impact of the Dodd-Frank Act, the banking reform measure Congress passed in response to the recession of 2008.

The bill, signed in 2009, faces its five-year anniversary Tuesday, and Rep. Jeb Hensarling of Texas, who chairs the Financial Services Committee, argues that the Dodd-Frank law went to far and overly restricted the financial industry.

He said the overhaul was essentially "Obamacare for our economy and your household finances."

"And just like Obamacare, Dodd-Frank has left us with fewer choices, higher costs and less freedom he said.

Instead of blaming the financial industry for the 2008 recession, as many liberals such as Sen. Elizabeth Warren, D-Mass., do, he said "misguided Washington policies helped lead us into it."

These policies, he said, "either strong-armed or enticed financial institutions into loaning money to people to buy homes they couldn't afford."

"It wasn't deregulation that caused the crisis," he said. "It was Washington's dumb regulations."

House Republicans, he said, offered an alternative to Dodd-Frank that "would have ended tax-payer funded bailouts and protected consumers" but Democrats blocked it in Congress.

Since Dodd-Frank, he argued, the economy has sputtered in a lackluster recovery, there has been less competition among banks and higher fees, and it is now harder for "credit-worthy Americans to buy a home."

"If we want strong economic growth, more freedom and an end to bailouts, it's time we commit to making sure this anniversary is Dodd-Frank's last anniversary," he said.

"House Republicans are working to do just that. Together, we can end Wall Street bailouts, have a healthier economy, and protect consumer choice."
