Four scenarios for Venezuela's growing political crisis

The political crisis in Venezuela has intensified since Juan Guaido proclaimed himself acting president, but what happens next depends on the United States and the Venezuelan military. In a country that has economically collapsed, with inflation forecast to hit a breathtaking 10 million percent this year, National Assembly chief Guaido said Wednesday he would "formally assume national executive powers" to end the "usurpation" of power by Nicolas Maduro. Maduro has accused Washington of being behind an attempted coup and has cut diplomatic ties.
