After reading the blog, it doesn't matter. As a "dignitary" they need to be cognoscente of every image they portray. In this case it is disrespect regardless of the context.
I agree with the premise, but also feel that approved behavior is a factor of circumstance. These are leaders, but they also human beings, in this case seated in a stadium of people reveling and celebrating the life of a great leader, in song and dance. This was not the somber funeral alluded to in every caption that goes with poking at the photo, this was a party, and for 3 world leaders to pose for a photo with each other in the middle of such revelry seems in no way out of line, particularly as they sit in their seats while others celebrate. Were it taken in a somber moment, or when they should have been paying attention to another speaker, perhaps. That was not the case when the photo was taken.
Obviously political predispositions and partisan politics plays a role in how many view this. I'm no fan of the POTUS, but I am a fan of the human condition, and the humanity displayed in this photo does little to dampen my faith in humanity. Obviously YMMV. :unconscious:
