In a memorandum to the PM today, the NSF said 16 years has completed since the Centre initiated the Naga peace process but there was not much progress in finding an honourable solution to the Naga political issue.
The NSF said the organisation knew the PM was engrossed with many issues confronting the government, but the Naga peace process was also equally important to be dealt with seriously, it said.
"We urge you to concretize the political talks and take a decisive step in bringing an honourable solution" to the Naga political problem, the NSF said.
