U.S. President Donald Trump opened a four-day visit to Scotland on 25 July by warning that illegal immigration is “killing Europe” and telling the continent to “get its act together.” Stepping off Air Force One at Prestwick Airport, Trump said European countries risked losing their identity if they failed to stem arrivals, calling the influx a “horrible invasion.” The president simultaneously renewed his long-standing attack on renewable energy, describing wind turbines as a “con job” that blight landscapes, harm wildlife and, if placed offshore, “ruin the oceans.” He added, “We will not allow a windmill to be built in the United States,” echoing earlier remarks this month that wind power is “very expensive” and “bad for planes and valleys.” Trump is scheduled to host European Commission President Ursula von der Leyen on Sunday and U.K. Prime Minister Keir Starmer on Monday at his Turnberry golf resort. European officials had not immediately responded to the comments, which come as the region debates migration policy and expands renewable-energy capacity.
