if ww3 wasn't starting it would be a big deal but I am not sure what effect it will have on the doller/yen ratio now. However, I closed my small yen carry yesterday so i guess I think it could mean the yen will move against the dollar.
economics was never my strong point and my head hurts too much to read it. But surely Isreal are going to drop 'the' bomb in a few days.... (not trying to get political BTW)
