As of today, the situation in Venezuela looks finely balanced. Madura still seems to have the support of at least the top brass in the military. Russia and China along with Bolivia and Cuba have continued to support him diplomatically. But with inflation now at 10million per cent pa, the economic situation is disasterous and seemingly can only get worse as long as Madura keeps in power and sticks to his current policies. The middle classes have always despised Madura but around 2m have already left the country. There are reports that in the poor barrios his support is finally weakening but so far not decisively.
Trump acted decisively in recognising Guiado and so far has said they will not pull all their Embassy staff out.
Mike Pence has been talking about leveraging the US s economic clout. Venezuela sells most of its oil to the US and has signicant assets there I suspect they are looking at whether the assets and income can somehow be diverted to the control of the interim government.
