The difference is stark, and Obama's actions were tested in June 2009. Iranians begged for help from the west, just like Jungarians in 1956, Czechs & Slovaks in 1968, but Obama didn't lift as much as a finger. He actually supported Ahmadinejad's suppression, just saying platitudes and generalities. They are 180º opposed alternatives. Obama is clueless, naive and believes in a formula ("engagement") that will never, ever work with Islamist Iran. Romney backs a formula of military power, and has shown his leadership isn't tied up by what's considered politically correct or apologetic about the USA's power on a global scale.
