All but 50,000 American troops in Iraq are due to leave by the end of August. The rest are scheduled to withdraw by the end of 2011.
The war of words over Iran's nuclear program kept heating up today. In Tehran, President Mahmoud Ahmadinejad warned other countries against trying to impose new sanctions on his government.
MAHMOUD AHMADINEJAD, Iranian president (through translator): If someone wants to act against Iran, our response wouldn't be like previous times. We will not advise or clarify or explain anymore. Definitely, there will be a counteraction that will make them regret, as usual.
HARI SREENIVASAN: At the same time, Russia, France and the U.S. called for Iran to stop enriching uranium to higher levels. They wrote to the U.N. nuclear watchdog agency and questioned Iran's claim that the uranium is only for medical purposes.
And, in Saudi Arabia, Secretary of State Hillary Clinton said the hope for a Middle East free of nuclear weapons is what's at stake.
HILLARY RODHAM CLINTON, U.S. secretary of state: If Iran gets a nuclear weapon, that hope disappears, because then other countries which feel threatened by Iran will say to themselves, if Iran has a nuclear weapon, I had better get one, too, in order to protect my people. Then you have a nuclear arms race in the region.
HARI SREENIVASAN: On Monday, Clinton also warned that Iran is moving toward a military dictatorship under the Revolutionary Guard. Today, President Ahmadinejad dismissed the criticism. He said, "We don't take her comments seriously."

It's part of a federal investigation of problems with gas pedals and brakes in millions of Toyota vehicles.

So, make no mistake. Whether it's nuclear energy or solar or wind energy, if we fail to invest in the technologies of tomorrow, then we're going to be importing those technologies, instead of exporting them.
HARI SREENIVASAN: The president also conceded, nuclear energy has what he called serious drawbacks. He said a bipartisan group of nuclear experts and leaders will try to speed up efforts to store nuclear waste safely.
Texas today challenged the U.S. Environmental Protection Agency on its finding that greenhouse gases are dangerous to humans.

The earthquake damage in Haiti may reach nearly $14 billion. That estimate came today from the Inter-American Development Bank. And Haitian President Rene Preval said, the huge job of clearing rubble will delay rebuilding.
He spoke to Associated Press Television News.
RENE PREVAL, Haitian president (through translator): I am going to tell you one thing. To take away the debris which is on the streets of Port-au-Prince, we need 1,000 trucks for 1,000 days. That makes it three years.
HARI SREENIVASAN: Preval also said the rebuilding must focus on investment in the provinces to discourage overpopulation in Port-au-Prince.
