The Jap and the German were not insane to declare war on the
war. Please, the Arabs are not insane for attacking the Isreal. You
need to read a lot about history of WW2, the middle east war, the
falkland war, the korean war, the vietnam war....to understand why
wars were started.
Threat has no impact on people insane, once the enemy is pissed
enough, or for whatever reason they want to destroy singapore, what
make you think that a nuke would stop them?
thinking that a nuke alone would save the country is insane. To
have a nuke in Singapore is a red carpet for trouble and probably
disaster.
