In his speech, a couple of weeks ago, the president tried to lower the flames but totally failed. The public neither any longer believes a word he says nor listens to his promises to introduce reforms. The president called on the refugees to return to their hometowns and villages, but they surely know they will have to face the army once they return. The only reform the public is willing to hear about is either the departure or the elimination of the president's family, or rather, the Mafia, which has taken over the country, its economy and the lives of its citizens.
'Lower the flames' appears unidiomatic to me, but that may be just personal. It can certainly be understood.
