"... acceptance of the Tak Bai massacre lawsuit in August offered Paetongtarn’s administration a chance to mitigate anti-establishment hostilities in the region." by Nurrisha Ismail November 13, 2024
(paraphrasing) While the Narathiwat Court found sufficient grounds for murder and illegal detention charges against seven former high-ranking officials related to the Tak Bai massacre, the government failed to uphold the rightful judicial process, and bring a measure of accountability for the killing at Tak Bai, could significantly hinder future peace efforts.
"Barriers to cooperation at both the insurgency and national levels can be ameliorated when conflict resolution policies are strategically designed to build consensus and uphold justice." (my bold)
"when" isn't apparently now.
The Muslim "South" has been under constant Kingdom of Thailand's State of Emergency (removal of constitutional rights) for decades. Relaxing enforcement while NOT raising or relaxing the State of Emergency entrenches mutual contempt and distrust by the Malay Muslim insurgents, especially in light of new and younger Malay Muslim insurgent groups not represented in the last decade of "peace talks" by the Thai government, largest insurgency group BRN and Malaysia.
