Completely agree that Klinsmann's long-term vision was the right one, or at least on the right track. But as a manager, his constant bizarre lineup and formation revisions were a very poor fit with the current crop of (entitled) players. I think they were basically confused, disoriented and pretty much demotivated. And I have no doubt that if Klinsmann continued at the helm, their record in the Hex would've been even worse...
...Although you're right, at least he would've played Johnson. But let's face it, Arena wanted to play with "his guys", doing it "his way" to prove he was still the man - classic case of ego triumphing over common sense. I mean picking Feilhaber over Johnson? Omar Gonzalez over Geoff Cameron? Just dumb.
Ultimately though, just another example of how ego and money rules U.S. Soccer. And while it's possible this setback becomes a catalyst for a complete teardown/rebuild, I think it's equally possible it could result in a big drop in public interest and revenue/funding for US Soccer, the MLS, developmental programs/participation, etc. Or maybe both will happen.
