World powers reached a historic deal to slow Iran’s nuclear ambitions in exchange for sanctions relief.

Several world powers have been in talks with Iran for more than a decade about its nuclear program. Now, after more than a year of missed deadlines, the United States, along with Britain, China, France, Germany, and Russia, have reached a deal with Iran to to curb its nuclear program in exchange for billions of dollars in economic sanction relief.

Iranian Foreign Minister Javad Zarif said the deal was “historic” and a “win-win solution,” but added it was “not perfect.” He said it marked a “new chapter of hope.”

Under the framework reached in April, Iran agreed to make significant changes to its nuclear infrastructure that would make it nearly impossible to build a weapon. The agreement outlines, among other things:

• The amount of nuclear fuel Iran can keep in the country for the next 15 years

• The kind of research and development it can do on centrifuges and other nuclear equipment

• The redesign of a nuclear reactor and enrichment site

• Regular access for international inspectors to all of Iran’s nuclear facilities

Iran insists its nuclear program is peaceful and says it is working with the United Nations’ International Atomic Energy Agency to clear any doubts. Critics believe the deal leaves too much of Iran’s nuclear infrastructure in place and overlooks Iran’s destabilizing role in the region. Israeli Prime Minister Benjamin Netanyahu called the agreement a “historic mistake.”

And a little extra.

The just-reached agreement must still get final approval from the U.N. Security Council. Iran’s supreme leader still needs to endorse the deal. And due to delays, Congress will have 60 days, instead of 30, to approve or reject the deal. Obama said he would veto any legislation that would block the deal.

President Obama granted clemency to 46 people convicted of nonviolent drug offenses.

The 46 men and women serving long sentences in prison for nonviolent drug offenses will have their sentences expire this year on Nov. 15 and be released early, the U.S. Justice Department said.

In a video posted to Facebook, Obama said, “I believe these folks deserve their second chance.”

“The latest round of commutations comes before Obama is set to visit a federal prison in Oklahoma on Thursday, the first such visit by a sitting U.S. president,” the Washington Post writes. Monday’s 46 commutations is the most in a single day since President Lyndon B. Johnson. Obama’s total of 89 commutations is more than the last four presidents combined.

What’s next?

The commutations by Obama are meant to serve two purposes. The first was to “correct the sentences of inmates serving time under old guidelines that no longer apply to newly sentenced prisoners and the other was to push Congress to enact changes to the criminal justice system a growing bipartisan coalition of advocates and
