 Thailand and Cambodia could blame their hostili­ties on the French. After all, the French drew up the border behind the century-old dispute. But merely blaming colonialism is the lazy way out. It was King Norodom who had invited the French into Cambodia, with the country eventually joining French Indochina in 1887 for protection against the Siamese (Thai) and the Vietnamese. Again, it was Cambodia’s attempt at registering an 11th-century temple on the border as a UNESCO World Heritage Site that was the first escalation of this cen­tury.

Thailand and Cambo­dia can keep denying casting the first stone in the current round. In the last analysis, it’s irrelevant. About 50 people had died in the July flare-up that US President Donald Trump had trium­phantly ‘ended’ with the “Kuala Lumpur peace ac­cord” which Bangkok even refused to call a peace accord.
