Former Defense Secretary Robert Gates asserts in a new memoir that President Barack Obama grew frustrated with U.S. policy in Afghanistan and that Vice President Joe Biden has been wrong on nearly every foreign policy and national security issue. He also accuses members of Congress of inquisition-like treatment of administration officials.

Obama approved the strategy of putting 30,000 additional troops into Afghanistan and placing Gen. David Petraeus in charge, even though some top advisers opposed the so-called surge he announced in December 2009.

Lindsey Vonn will miss the Sochi Olympics because of a right knee injury, leaving the Winter Games without one of its biggest stars.

The 29-year-old skier from Vail, Colo., announced her decision Tuesday, exactly one month before the opening ceremony in Russia. Her personal publicist, Lewis Kay, said in a statement Vonn will have surgery "shortly."

Arsenal winger Theo Walcott will miss the World Cup for England after being ruled out for six months on Monday with a torn knee ligament, an injury that also deals a major setback to his club's hopes of winning the Premier League.

Walcott ruptured the anterior cruciate ligament in his left knee as he made a tackle toward the end of Arsenal's 2-0 win over Tottenham in the FA Cup on Saturday.

Top seed and defending champion Agnieszka Radwanska of Poland was defeated by American qualifier Bethanie Mattek-Sands 7-5, 6-3 in the second round of the Sydney International, a key warm-up tournament for the Australian Open.

The Cleveland Cavaliers traded Andrew Bynum in time — and got an All-Star in return.

Former U.S. Homeland Security Secretary Janet Napolitano is ready for the focus of the Sochi Olympics to shift from security concerns and terrorism threats to all the athletes who will be competing.

Yet Napolitano, who is leading the U.S. delegation at the games, fully understands the daunting task of organizing an event of this magnitude — especially in the wake of two suicide bombings last week in the Russian city of Volgograd, 400 miles (640 km) from Sochi.

In Iran, free condoms and government-backed vasectomies are out, replaced by sermons praising larger families and discussions of even offering gold coins to the families of newborns.

Having successfully curbed birth rates for two decades, Iran now is promoting a baby boom to help make up for its graying population. But experts say it is difficult to encourage Iranians to have more children in a mismanaged economy hit by Western sanctions and 36 percent inflation.

Huawei, China's largest cellphone manufacturer, is releasing a phone that can be thought of as the inflight refueling system of the mobile world: it can be used to recharge other phones.

The Ascend Mate2 has a 6.1-inch (15.5-centimeter) screen, making it more than twice as big as an iPhone 5. It's almost the size of a tablet, giving rise to the half-joking term "phablet." It's the successor to a phone of the same size launched last year.

LG will bring the software that once powered Palm's smartphones to the majority of its Internet-connected TVs this year.

The South Korean firm unveiled webOS-based smart TVs at a trade fair Monday in Las Vegas, less than a year after it bought the operating system for smartphones and tablet computers from Hewlett-Packard Co.
