Remember, the Europeans think there is a gangster with an AR-15 on every street corner in the US.
I would say we are "medium" experienced travelers, a little over 40 countries including third world like Ethiopia, Myanmar, Egypt, etc. Sure, some countries have more problems than others, but in almost all cases they are localized (Tahrir square) in cities or well away from tourist areas (Rohingya persecutions). Injuries and other major risks to tourists are statistically negligible. In most case, too, the governments are desperate for tourist revenue and go to great lengths to protect us as valuable revenue sources. Egypt actually has "tourist police" whose job it is to help and protect tourists.
Of course there are a few places to avoid, like maybe South Sudan, CAR and, recently, northwest Ethiopia, but most are not usual tourist destinations anyway.
Re CYA, yes on that and on politics. Warnings about the West Bank, for example, are a total political joke.
Morocco with a guide? Near zero risk. Be careful at the Hassan II Mosque mosque. Some really irregular steps there.
