Meanwhile, back in Washington DC, President Donald Trump was again bragging that the military option was still on the table, in his press conference with Brazilian counterpart Jair Bolsonaro. Trump is bluffing or not yet up to speed with being apprised of Russia's red line.

The meeting in the Italian capital between US "special envoy" on Venezuelan affairs Elliot Abrams and Russia's deputy foreign minister Sergei Ryabkov had an air of urgency in its arrangement. The US State Department announced the tête-à-tête only three days beforehand. The two officials also reportedly held their two-hour discussions in a Rome hotel, a venue indicating ad hoc arrangement.
