The problem with Photoshop is that everyone else has it. So, in a pissing-contest photo, in which half your military hovercrafts look exactly the same, it takes little zooming or deduction, or even the CIA, to work out North Korea's militaristic might, might not actually be quite so.
The US' new Defence Secretary responded with propaganda of his own. Chuck Hagel's bolstering Alaska-based missile defence systems, and the ominous photo of a US stealth bomber flying above South Korea, was either a much better Photoshop effort or devoid of air-brushing.
It's easy to snigger at North Korean propaganda. It's easy to discard Kim Jong Un as a chubby, narcissistic, (bizarrely) Dennis Rodman-pandering, deluded funster in a land of the oppressed and hungry.
But nuclear proliferation isn't a joke. And though a war-wary US President may be unenthused to have to check his rules of engagement, there are only so many taunts and tests that will keep the US public satisfied with sanctions, and South Korea or Japan from really getting serious.
It's worth a close watch, and on more than just YouTube.
