Just an off-topic discussion. In particular, I'm referring to the UK's letters of last resort (
Wikipedia link if you're unfamiliar with them). Basically, you're in charge of a country (etc) and have the option of (at least attempting) to get revenge on whomever may destroy your country. If you were killed and your country destroyed, would you prefer to (attempt to) bring down those who caused your demise? No one would know of your choice unless it was ever executed. It's like pulling the trigger on your own killers.
If it was your choice, would you do it?
EDIT: A similar example of this capability was the Soviet era "
Dead Hand". However, it differs in that it's not kept secret, as is the choice given in the UK's letters of last resort. The intent of the Dead Hand was as a nuclear deterrence and for revenge.
