If I recall correctly, your question was "What do you think?" I think 2 things:
First, I'm particularly angry that you post a link to a video that contains imagery of a human decapitation without warning about this. I'm aware that this stuff is out there on the web, but since I find it repulsive in the extreme, I have avoided it. You removed that choice from me, deliberately no doubt, since to publicise this fact would probably have resulted in the question being banned. That p'd me off first and foremost.
Second (and entirely unrelated to the above), the content of this video is an attempt to frighten those that may object to current military action. It's not just the military action either, what it is saying is that if you don't agree with our leader's vision of the future, then you are a fool and you should shut up. Dissent is not allowed.
If this were a parody of an Al Qaeda propoganda video while simultaneously poking fun at the Americans, I think it might be particularly inspired. However, since I'm pretty sure it isn't, I find it's message troubling. I'm not convinced by its message but I fear that some people that feel that current actions are wrong will be convinced that they shouldn't have that opinion because it is unpatriotic and will help us loose the "war on terror".
I think that link connects to an objectionable load of rubbish.
