What happens next in Venezuela appears to hinge on the actions of the country's military.
For now, high-ranking officials remain supportive of Maduro's government.
Guaido, who is calling for free and fair elections to be held in Venezuela as soon as possible, urged the military to disobey the government.
Political analysts told CNBC on Thursday it was certainly possible that escalating pressure from the international community could encourage lower-ranking officials to turn against Maduro's government.
"One month ago, I would have said this was not possible. But it feels different this time," Gabriele Saade, a research and project coordinator with La Mejor Venezuela Foro, a political think-tank based in Caracas, said Thursday.
"I think the costs of supporting the government are higher and higher every day," she added.
