I am very happy about this.
Then again though, there are two things that play on my mind:
- Will there be a retaliation?
- Will it change anything?
To be honest I think the answer to both is 'unlikely'. They would have planned for the eventuality of his death ever since 2001, so I doubt it'll change anything about the running of a terrorist organisation. Secondly, if we are to believe the press, terrorist attacks are thwarted by secret services a lot more than we realise. It will probably just be business as normal, but whether they are successful is another question.
