Are you assuming Powel lied? Apparently you do not have all the info you need to understand fully if you do. Second, while I tend to be distrustful of government, I am not willing to jump to full blown conclusions simply because I do not like the decisions. You are making claims (i.e. Assad's guilt is anything but clear) without knowing everything our government and other nation governments know. It is not just the US that is saying Assad is guilty.
By the way, where do you think Assad obtained these chemical weapons he has admitted to having?
No, I do not assume Powell lied. I believe he was misled by our government
at that point in time. Unlike you, apparently, I remembered the chain of events at the time and also did some studying into the incident.
Also, who is more in need of info, me or you? I admitted that Assad's and Putin's guilt was "not clear". That is an expression of not knowing on my part.
You are the one who is making the assertions, acting as if you categorically believe our government's line.
No, it is not just our government making these claims. Agreed. Several of our lap dog allies are as well.
Like others have said, you need to do some more research. Might I suggest also you read from a wider spectrum of sources.
