Without knowing who made this video or what their agenda is, it's hard to judge it.
Is the translation accurate? Is it the work of a radical element who would promote holy war? (We certainly have them on "our" side as well.) It's important to remember that the thousands who are part of the radical islamic terrorist groups are not representative of the hundreds of millions of muslim faithful in the world, any more than the Branch Davidian was representative of Christianity.
We know that there are radicals on the terrorist side who have committed horrific deeds. Whether the most effective way to stop them was a war was/is a serious question - we answered it 5.5 years ago with the war solution, with very mixed-to-poor results. Then again, maybe keeping the terrorist element engaged "over there" has been worth the great price our country has been paying.
One of the most frequently heard lines of the post 9-11 days and months was "if [insert almost anything, from 'we don't go on vacation' to 'we give up our SUVs] then the terrorists have won!"
I have long been of the mind that the terrorists did win - the battle of 9-11. Beyond that, I'd say, if we can be tempted into a war against the wrong enemy that will cost us many lives, cost us nearly a trillion dollars (so far), serve as a recruiting event for the real enemy, provide a stage on which we can diminish our standing among allies and divert attention, funds and effort from a more effective approach to international terrorism ... then the terrorists have "won."
