I’ve been reading the Rolling Stone magazine piece that brought down General McChrystal and feel very unnerved by it. I know that the consensus dictated that, after remarks made largely by members of McChrystal’s team, the General simply had to go. But a number of things occur to me. Firstly, is America sure it has enough top generals and is doing so well in Afghanistan and Iraq that it can simply dispose of any general tripped up in such a – pretty sneaky – way by the media? I tend not to have much sympathy for politicians caught like this....
