WASHINGTON (AP) — President Donald Trump’s war against Iran is stretching the limits of U.S. aircraft carriers and leaving the western Pacific without one of the key American warships as China shows more signs of aggression. The USS George Washington is departing the Pacific and expected to replace the USS Abraham Lincoln in the Middle East amid growing concerns about mental health and supply issues aboard the long-deployed carrier. The Lincoln has had its time at sea extended from its original May return date to support operations against Iran. The lack of a U.S. carrier in the Pacific may be short-lived if the Navy deploys another in the next couple of months. But it shows how the open-ended operations with Iran are running some American sailors ragged, analysts say, while the Trump administration further retreats from the Asia-Pacific region and focuses on the Western Hemisphere.“The administration says that the Pacific is supposed to be the most important behind the Western Hemisphere,” said Greg Poling, director of the Southeast Asia Program at the Center for Strategic and International Studies. Instead, the U.S. is “doing the exact opposite” of its previously expressed goal of pulling out of the Middle East.American allies in the Pacific are unsettled over the unpredictability of the Republican administration, Poling said, while Beijing “is quite happy with U.S. distraction, with the frustration of U.S. allies and partners.”
