Then, of course, there were the tweets:
Despite what you have heard from the FAKE NEWS, I had a GREAT meeting with German Chancellor Angela Merkel. Nevertheless, Germany owes.....— Donald J. Trump (@realDonaldTrump) March 18, 2017
Germany's defense minister has rejected claims from that Germany owes NATO "vast sums of money."...vast sums of money to NATO & the United States must be paid more for the powerful, and very expensive, defense it provides to Germany!— Donald J. Trump (@realDonaldTrump) March 18, 2017
In a statement released on Sunday, Ursula von der Leyen said "there is no debt account in NATO. To relate the 2% defense spending that we want to reach in the next decade solely to NATO is wrong.
"The defense spending also goes to UN-peace mission, into European missions and towards our contributions to the fight against ISIS terrorism."
Only five of the bloc's 28 members -- the US, Greece, Poland, Estonia and the UK -- meet the alliance's target, which NATO also terms a "guideline" in its annual report.
Will Trump use the cover of Germany's failure to spend 2% of GDP for the military a reason to impose tariffs on a Merkel-led Germany that he seemingly does not like?
Also, note in the chart above that broke Greece spends the most on the military as a percentage of GDP.
