(Some) Thais fed up with royals: In their largest show of force to date, around 18,000 young Thai activists took to the streets of Bangkok on Saturday to rally against the government and demand sweeping changes to the country's powerful monarchy. The protesters installed a gold plaque declaring that Thailand belongs to the Thai people, not the king — a brazen act of defiance in a country where many view the sovereign as a god and offenses against the royal family are punishable by up to 15 years in prison. Activists also got the royal guards to accept a letter addressed to King Vajiralongkorn with their proposed reforms. We're watching to see if the Thai government — made up mostly of the same generals who took over in a 2014 coup and then stage-managed last year's election to stay in power — continues to exercise restraint against the activists. So far, some protest leaders have been detained but they are growing bolder in their defiance of the military and the royal family, the two institutions that have dominated Thai politics for decades. Prime Minister and former army chief Prayuth Chan-ocha is in a tough spot: many young and liberal Thais will hate him if he cracks down hard on the peaceful protesters, but not doing so would make him look weak in the eyes of his power base of older, more conservative Thais who still venerate the monarchy and are fine with the military calling the shots in politics.
