The article makes, or at least reports, the following claims about the tapping of Merkel's phone: (1) it began in 2002 (when, yes, GWB was in office), (2) Obama was told about it in 2010, and (3) at that time he approved it and allowed it to continue.
If all this is true, then it seems to me it's perfectly fair to "pin it on Bush" and to blame Obama for the fact that it continued past 2010.
It also seems worth remarking (a) that actual evidence for the claims seems to be in short supply, and (b) that if they're correct it's pretty weird that Obama wasn't told until 2010 that the NSA was tapping the phone of the leader of a major foreign nation allied with the US.
