Democrats have been critical of Romney for making no mention of the war in Afghanistan when he accepted the Republican nomination in Tampa, Fla., last week. He previously criticized Obama for setting a public date for the withdrawal of U.S. combat troops from the war.
Romney also has faulted Obama for allowing the government of Syrian President Bashar Assad to remain in power. Yet his aides have refused to say for a week if he agrees with French President Hollande’s promise to extend diplomatic recognition to a provisional government if Syrian rebels form one.
