I'm pretty sure that billion dollar army tech is not connected to a civilian Internet network. I find the idea of a F-35 asking you for the wifi password pretty funny.
Now, if you want to disrupt the Internet connection of the army of a sovereign nation, good luck. This whole aspect of the article is not very credible.
On the other hand, If the U.S. decides to render the F-35s unusable by forcing those running the update server to stop service or by blocking all incoming communication to those update servers, it's going to be a terrible precedent. I can only see that happening in some very dire scenarios. Sabotaging military tech of an allied nation is not something you do without expecting consequences.
I think he's on to something... In these times of political and economical uncertainty, we should bring back ancient Rome colosseum style games. Modern fighters taking on wild animals for glory. Give the masses something to get excited about.
Let the man get himself dismembered by a gorilla as part of a bigger event with deadly races and feats of human strength.
