"Such a military invasion will end in the legitimization of the dictator [Venezuelan President Nicolas Maduro] because he always looks for an opportunity to create an image of an aggressive enemy to boost his power," Duque told the Caracol radio broadcaster.
On Tuesday, the National Constituent Assembly of Venezuela issued a statement demanding the immediate resignation of Almagro over his remarks. Maduro called Almagro "garbage" and vowed to repel any possible invasion.
Venezuela has been engulfed in a deep economic crisis, with hyperinflation and food shortages. Besides, the country has been facing mass protests. As result, Venezuelans are seeking asylum in other countries, with over 2 million people have left Venezuela since 2014, according to the United Nations. Some one million of them remain in Colombia.
