I don't think the government was behind it. Honestly, all damage like that has to be paid for, which takes money from Congress' "extracurricular activities.. Do I think that's the real reason they sent our military over there? No. I think that the terrorists just gave the government an excuse to go over there, in order to try once again to get the oil.
Everything in the media and what they portray is only explicit, meaning their is always implicit(insider) reasoning. Just like any war, people believe that oh yeah we are against all that but the whole economy depends on it. It is important for some of the public to fall into this propaganda so they have to use their minds, which traps them. Just as people mourn over celebrities dying when people in there own community die or even their neighbor and no one even knows or cares. It's all a mind game.
