Today is the anniversary of 9/11. The world changed that day, 10 years ago. War on terror officially began that day. But is the world safer today?
I think it is not. Terrorism comes in many forms, as we saw recently in Norway. The bombings in Russia or UK were also a proof of that. Al-Qaeda has lost their leader and their network is not the same it was 10 years ago which makes me to believe that operation similar to 9/11 would be hard to carry out. There just might not be organisations with such capabilities anymore.
Still, lack of such attacks is not a proof that such capabilities don't exist. As long as there are different ideologies there are those who are willing to fight. We just have to hope that initiations like the Arab spring will carry the power of words further than the power of weapons.
