Unfortunately, I think it's far from over
He was the charismatic mouthpiece of the al-Qaida, but there is still an al-Qaida, and there are still leaders up in the ranks, ready to take over if something like this happened. It was bound to happen sooner or later, and they've had 10 years to figure out what they were going to do if and when it did. bin Laden's health has been failing for years, and you bet he would have a backup plan to keep the organization running.
I've noticed a huge difference between American and Canadian new sources! The USA seems to be cheering and celebrating, and Canada seems to be saying "Okay, get ready for some backlash" Personally, I think that will be inevitable. You know how Americans felt to see the celebrations in the streets in the Middle East after 9/11? The al-Qaida will be feeling the same way to see the American people celebrating the death of their leader. I think it's just adding fuel to the fire
