Staffan de Mistura quotes:

Freedom of speech does not mean freedom of offending culture, religion or traditions,

In every conflict, some rhetoric and posturing, so we should take that aside. When facts is that everybody is exhausted and that no one believes that there is a military solution to this. The solution must be a political one.

Sometimes there is a common threat that can produce a common interest in putting aside all the differences in trying to find a constructive solution.
