Jadue has criticized the foreign policy of President Sebastián Piñera, arguing he was too friendly towards conservative U.S. President Donald Trump. During the Crisis in Venezuela, Jadue alleged that Piñera's government was working in concert with the Trump Administration to overthrow President of Venezuela Nicolás Maduro. Jadue stated in 2020 that he condemns "any type of violation" of human rights following the release of findings by the United Nations that the Maduro government engaged in extrajudicial killings and torture.
