There are certain constants in Thailand: the drenching monsoons, the grand openings of new shopping malls and the rumors that the Royal Thai Armed Forces are plotting another coup.

For weeks now, student-led protesters across Thailand have taken to the streets every few days, calling for a new constitution with authority over the monarchy, an end to the persecution of the political opposition and the resignation of Prime Minister Prayut Chan-ocha, the retired general who led the most recent military coup, in 2014.

Some earlier anti-government movements in Thailand were silenced by gunfire, with dozens killed most recently in 2010. While the security forces have not cracked down violently on these peaceful rallies, it’s unclear how long such restraint will last. Nor is it certain how long the army is willing to stay in the barracks, plotting against Prayut, who was once one of their own.
