Dec 12 (Reuters) - Venezuelan opposition leader Maria Corina Machado on Friday promised political change after slipping out of the country in secret to collect the Nobel Peace Prize, as the shock waves intensified from the Trump administration's seizure of an oil tanker earlier this week.
That escalation came on the heels of a large-scale U.S. military buildup in the southern Caribbean as President Donald Trump campaigns to oust Venezuelan leader Nicolas Maduro, pushing relations to their most volatile point in years.
