I get where Tuco is coming from, but I think he is equating knowledge with intelligence. We have more access to (and outright learned) knowledge than at any point in human history. That is undeniably true. But there is a decided absence in truly new concepts and innovations in recent decades, just tons of amazing refinements on the efficiency of existing ones. At some point, if we keep doing the shit we are, we are going to hit another tipping point like Europe did with the Dark Ages where we will HAVE to be inventive again, rather than derivative. I just hope we haven't fucked things up with religion, greed, and laziness too far to recover from it.
On topic, I think you absolutely do have war crimes investigations and (if evidence merits) trials. Maybe his Gitmo fever has made him forgotten this, but our country has this concept of due process, so an investigation does not imply guilt. And if Israel wants to keep itself on some high horse, it is in their best interest to have an impartial investigation clear them of wrongdoing in this case.
