Question

why did the united nations have difficulty in drafting a definition of terrorism?
many of the member countries harbor terrorists.
the characteristics of terrorism are hard to define.
some military activities have been mislabeled as terrorism.
the terrorist label has been indiscriminately applied to many groups.

Explanation:

Core disagreements stem from the fact that states often disagree on which groups/acts qualify as terrorism; what one state calls a "liberation movement" another labels terrorism. This leads to the label being applied inconsistently across member states, making a universal definition unachievable. The key barrier is this indiscriminate, subjective application of the terrorist label by different nations.

Answer:

The terrorist label has been indiscriminately applied to many groups.
