Changing things is not easy, and I say this without any irony. It is not that someone does not want to, but because it is a hard thing to do. Take Obama, a forward-thinking man, a liberal, a democrat. Did he not pledge to shut down Guantanamo before his election? But did he do it? No, he did not. And may I ask why not? Did he not want to do it? He wanted to, I am sure he did, but it did not work out. He sincerely wanted to do it, but did not succeed, since it turned out to be very complicated.
