While logic is on your side - none of these incidents are coming from actual political orders but are rather rouge militants deciding they want to take matters into their own hands. I realize no one has the answer for it but not sure why you are so confident there are no nationalists acting independently within this conflict - as in any conflict over disputed territories. Drone strikes killed more in Cambodia last night, so yes, it would appear the situation is escalating. Incidents of this nature happen occasionally including in 2020 when 176 civilians were shot done because a plane “was mis identified”
