Let's take a look at the original target list of what was supposed to be attacked.
United States, Canada, United Kingdom, Israel, Saudi Arabia (only Government), China, Italy, France, Germany, Kuwait (only government) and Qatar (only government)
Hackers News Bulletin released a live list of all the damage done as part of OpPetrol, and it's a rather short list. Let's run through the list and look to see if Anonymous actually succeeded in their operation.
Better grab some popcorn, this is going to be quite entertaining.
This appears to be a local government website in southwest Saudi Arabia. However, the main landing page itself was not defaced, but instead a "hidden" webpage was placed, most likely days in advance. Trend Micro has a great writeup on how these "timed attacks" really aren't timed at all.

In conclusion, the above incompetency shows just how few technical minded members of Anonymous remain. Most of what's left are script kiddies who don't even understand how the Internet works, and think that posting IP addresses and browser versions is equivalent to having "dox" on everyone in the USA.
