You're just restating the problem. I don't understand how "Therefore the value of the Red Cross symbol must be protected as it is desperately needed" follows from "[As an example of an increasingly unstable world,] … there have been 162 fatalities."
2. The Red Cross helps these people.
3. Their symbol is a tool which improves Red Cross's ability to help.
4. Misuse or casual use of the symbol dilutes its utility.
5. Therefore, please cease its casual use.
