Possibly. They had to pick the guy with the most islamic possible name. Now middle america gets to see on the news how we busted someone called Mohamed Mohamud for terrorism, breeding even more anti-islamism among americans (if that were possible).
More likely though it did next to nothing to quell islamic terrorism in the world. Sting operations like this cost millions of dollars to execute. That wasted money could have been spent feeding the hungry, researching solar energy or nanotechnology, helping to pay off the national debt, etc.
