I Am Confused By This "War Heroes" Poster — Please Esplain?S

I can't figure out what the message is supposed to be behind this poster for a new comic book called War Heroes by Mark Millar, the scribe behind the pointed political series Civil War. Is it a pro-McCain poster? An ironic anti-McCain poster? An acknowledgment that Obama is realistic and therefore probably better at dealing with, you know, reality? A way of showing that political leaders have also taken a stance on superpowers? I'm only half-kidding here, people. I genuinely have no idea what the message is behind this thing. Please help.
