I think intimidating is the wrong word. Disrupting is the right one.
The video above showed the planes circling the hotel in the morning. I actually don't have too much of a problem with that, although jets are fudgeing noisy.
The fighter jets in isolation would be fine, as you say it was just a bit of a stunt and probably relatively good natured.
The fireworks in isolation would be fine as well.
But when you start to add everything together it gets a bit much. The thing I have most of a problem with is actually the issue with the flight being redirected to Chile. That goes beyond banter and shows the Peruvian government actively disrupting preparations.
