He's a little more high profile than Gerald Bull. Perhaps a discreet plane crash might be fitting.
It's preferable that Kerry would be indicted, tried, convicted, and sentenced to hang. This shows that justice can still be accomplished in the United States; it would demonstrate a process that could be applied to other traitorous Demonicrats; and it would serve as an example for the next generation, when they become adults, on how to deal with traitors.
Gerald Bull had a little difficulty with his priorities.
Apparently “staying alive” was not near the top of his list.
Then again, maybe MI-6 killed him once it was realized just how risky that little venture truly was.
