There's no way that James Bond could kill Rambo, even with a WASP knife. Rambo has been shot at and missed more times than Bond has. Rambo has endured more torture tactics than Bond has. Rambo has killed more bad guys with his shirt off than Bond has with his shirt on.
Bond's character has been watered down over the years, and they're running out of ideas for gadgetry. What's next? Super itchy pants? A Slurpee machine in the glove compartment? Special gas sensitive underpants that fires a death ray when Bond points his rear end at someone and poots?
