Captain America has always been a political figure for me. Most comic book heroes deal with purely social issues, but CA comics always seemed to have more political undertones than other comics, even more so than the obvious influences in the early Superman series.
As my country celebrates its 231st birthday, I am reminded of how it has withstood its enemies. And much like the depicted flag and shield, the USA is still very strong, although it may appear to be tired and battle worn.
Happy 4th of July to my American brethren.
