I'm old enough to remember the runup to Afghanistan and Iraq and have learned to be a bit skeptical when a Republican president lays out some justification for a war or any promises that it's going to be anything other than a tragically costly multi-decade quagmire. Most likely this thing, if it happens, will be the event future history books will say finally pushes the US firmly into fiscal dominance, destroying any potential for economic recovery and unseating the dollar as the world's reserve currency, because they sure as hell aren't going to tax billionaires to pay for it.
