Is there any possibility to join Singapore defense forces es for other nationalist?

Well I don't think it will happen anytime soon. World War II started because of World War I (basically German people didn't like their countries punishments). And since world war III hasn't started because of world war II it could be quite a while.

Also, just because the United States goes to war with someone like North Korea doesn't mean the rest of the world will, so I don't consider this theory very likely. For example, Russia has no interest with North Korea, most of Europe has no interest in North Korea. Austrailia might, but that's only because they are very close geographically.

So really I have no idea, but I don't think it will be for a while.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
