How to pray for a corrupt government involved in drug trafficking?

Venezuelan government/regime is destroying the country through corruption, drugtraffiking to the USA and Europe, murder, kleptocracy, unjustified imprisonments. The government palace is full of symbols and objects of demon worship and "santero" altars. They are starving the population of the country without water, electricity, gasoline, security, health care, justice, etc. Venezuela seems to be the pre-apocalyptic laboratory! Should I consider them as the authorities imposed by God, in order to pray for them and not against them? How should I pray?
