North Korea and USA could escalate into a biggy. But hopefully Obama will have more integrity than Bush.
I think if the NK and USA hatred gets worse, and a war comes along, I think a lot of countries cold be dragged into it, for example, Britain could get dragged in it by USA, and North Korea could maybe call on their communist counter-parts China, and maybe even the USSR, and we all know that Putin is a mean bastard.
However back on subject with Israel and Iran. I do not think Israel will want to drag themselves into another war just after the Lebanon situation has calmed down.
On the other hand, I feel that something is going to need to stop Iran soon, or maybe they could get out of hand.
I don't know much about politics at all, apart from the British Government are a bunch of hypocrites.
