Don't miss Sandman's point.
Apart from the "brilliant" word, that for sure hurts, I think it is crucial that all of us understand what we are facing.
I honestly think this is the prelude of WWIII. As somebody said, this will not be a conventional one. No one can attack US & allies, or US alone on a conventional way. Terrorism is the only way to really hurt us. You can insult the enemy, but one thing you should never do is let that insults blind you. We are facing a threat to our way of life, and our way of thinking. That is quite the same all over western countries.
These beasts will do whatever it takes (let it be killing civilians no matter if they use an airplane, a chemical, a biological or whatever weapon within his means) to overcome us. They are ready to face self-anihilation and now we tragically know they CAN organize and arrange complex plans. Do you feel better calling them cowards? So be it. I rather call them ENEMY.
These people has the willing and the means to do terrible, and I mean terrible, things. Wether they are cowards, villains, stupid, tards, whatever... is irrelevant. The only important thing is to realize that there are 2 clear sides on this issue. One is evident, vulnerable. The other one is sneaky and criminal. We must prepare and be ready. And the first task to success is knowing your enemy. We have a small taste of them in Spain. Let me tell you they are not stupid, and they are not cowards. They are evil.
