As the world becomes more dangerous and chaotic it is wise to rethink touring plans. The English speaking countries are generally safe, as are Scandinavia and Northern Europe. The rest of the planet is less safe but it varies.
Even in the good old USA , there are bad places. Avoid the border regions and the inner cities.

In some places touring cyclist are seen as an easy mark, and they travel on predetermined routes, it is pretty easy to set up an ambush. Maybe take the bus on those places.
