Garry Kasparov: Russia Worries About the Price of Oil, Not a Nuclear Iran - WSJ.com

"If the U.S. is serious about preventing Iran from getting a nuclear weapon, then Mr. Obama must get to the point and state the penalties unequivocally. Repeating over and over that it is 'unacceptable' has become a joke. For more than 10 years a nuclear North Korea was also 'unacceptable.' If Mr. Obama says the U.S. will do whatever it takes to prevent Iran from attaining a nuclear weapon, then we will see if Tehran blinks. At a minimum, the White House should publicly promise that any attack on Israel with weapons of mass destruction will be treated as an attack on American soil and urge NATO to make a similar commitment."
