Carter was a pussy and our enemies (and some allies too) laughed at us.
Obama = Carter
Actually I'd say most of the world has respect for the USA again since Obama came along. Can you imagine Sarah Palin as President? Then you''d see the entire world laughing.
If anything, he's taking a harder stance in Afghanistan and Pakistan than Bush; is still in Iraq, and has not closed Guantanomo, so I don't think he's acting like a weakling.
