If you are trying to compare WWII-era propaganda to this satire about the Obama campagn, the only response I can think of is “Whaaaa–?” Propaganda uses religous imagery to persuade; satire uses religious imagery to make fun of those doing the persuading. They have opposite purposes, so it is illogical to act like they are one-and-the-same. Bottom line: It’s a joke. Don’t take it so seriously.
Also, I like Top Gear, but I’m more partial towards Bargain Hunt.
