US Secretary of State Mike Pompeo cancelled a Germany visit Tuesday hours before he was due to arrive in a move that did little to alleviate diplomatic strain between the traditional allies. The no-show came at a time when President Donald Trump has repeatedly criticised Chancellor Angela Merkel's government on migration, trade, Russia relations and what he considers Berlin's insufficient NATO spending. Pompeo had been due to meet Merkel and Foreign Minister Heiko Maas later Tuesday.
