Cambodia-Thailand border conflict: Why the escalation despite Trump-brokered deal?

This as the old guard on both sides enjoy free rein: Cambodia's Hun Sen, who's officially no longer head of government but whose shadow looms large, and Thai generals who have a habit of taking the lead in times of crisis.
