No one is suicidal, but escalation don't always work according to logic. It's people making decisions, and people are emotional. Another thing to consider is, if you're the one up top, perhaps pressing the red button and living in a nice warm bunker with staff serving you is much better than being ousted, voted out or accused of corruption and facing the probability of going to jail (depending on the country). So I wouldn't be so sure we're immune to the global war just yet.
