Iran nuclear deal

The tentative deal to contain the country's nuclear program in exchange for more economic freedom is a wait-and-see moment for Western firms.

Years of sanctions and economic stagnation in Iran have hampered its oil sector, forestalling an immediate surge in crude oil exports.

House Democrats are likely to be key in preventing Republicans from scuttling the deal.

A number of key restrictions against the country, particularly those related to terrorism and human rights, remain in place.

"I hope that Obama will study the reality of Iranian activity in the region and begin to push back against Iran’s ambitions with more alacrity than ... so far."

Just 5 percent of those surveyed said they had "a lot of trust" in Iran, while 55 percent said they would not trust Iran to abide by the deal.

Iran's market will open up for international investment, but not right away.

In 2009, Iran already had 7,200 centrifuges, meaning that, even then, Iran could produce two nuclear weapons a year, weapons experts said.

The deal with Iran could easily be reversed by the next president when Obama leaves office, causing any hope for a lasting impact to crumble.

Legislation passed in May will make it very difficult for the Republican-controlled Congress to reverse the president's deal with Iran — but that won't stop them from trying.

Israeli Prime Minister Benjamin Netanyahu reacted to the deal on Tuesday, saying that the "desire to sign an agreement was stronger than everything else.”

President Obama, in an early morning address, sought to strike a cautiously optimistic note while stressing that the Iran nuclear deal is “not built on trust, it’s built on verification.”

U.N. Secretary General Ban Ki Moon says the deal will lead to greater understanding and cooperation in the Middle East.

Iran and six world powers arrived at a deal Tuesday morning to limit the former's nuclear program in exchange for the suspension of sanctions.
