Sarah Palin says that if President Barack Obama "played the war card," he could improve his chances of being re-elected.

Palin says that declaring war on Iran or showing stronger support for Israel might convince voters that Obama is tougher than they think on national security and doing all he can to protect the U.S.

Otherwise, according to Palin, Obama won't be re-elected if he continues on his current path.

Palin was interviewed on "Fox News Sunday" _ the network where the former GOP vice presidential nominee is a paid commentator.
