Spanish Prime Minister Pedro Sanchez addressed the nation on Wednesday following President Donald Trump's threat of a full trade embargo after Spain denied the U.S. use of its bases in the war against Iran.
Spain's position, Sanchez said, could be summarized as, "No to war."
The Spanish leader condemned the "indiscriminate" bombing by Iran of other nations in the region. He said that the objectives of the U.S. and Israel were not clear and warned about the "serious consequences" of a potentially long war for the global economy and the cost of living for people in Spain and beyond.
Referring to the 2003 invasion of Iraq and subsequent regional instability, Sanchez said his government's position was based on "not committing the errors of the past."
"No-one" supports the theocratic regime in Tehran, Sanchez said, calling for an end to hostilities and a diplomatic solution "before it's too late."
