Mr Trump accused Berlin of falling short of its NATO commitments during a meeting with Polish President Andrzej Duda at the White House yesterday (June 12). The US President demanded that they increase their defence spending from one percent to two percent of gross domestic product (GDP).

But Berlin has only pledged to increase spending to 1.5 percent by that date.
