To be honest I find it a rather brilliant ad. Ofcourse are the (conservative) Americans going crazy on this, but from another point of view you could also say the statement of the ad has created its point of awareness. At least, in de the rest of the world, hehe. People are talking about it. Maybe on the short term only about the 9/11-part (the bad timing, sigh), but later on this might switch more to the tsunami/nature-part, even if it's subconscious.

All in all I still understand why WWF rejected this ad from DDB in the first place. It could do harm to the relations with their American investors, which I assume are quiet a lot.

Worst story I've read about this case so far is that DDB Brazil sacked the whole creative team who worked on this ad for them. I sooo hope this isn't true. Would be a step back in the liberal world of advertising...
