Germany owes NATO vast sums of fund and must pay the U.S. more for the powerful, and very expensive defense it provides, President Donald Trump tweeted Saturday.

Trump complained in his first tweet about fake news, after his refusal to shake German Chancellor Angela Merkels hand upon request at the Oval Office was widelyreported, before moving on to construct his wild claim on NATO debt.

Trump has repeatedly complained that the U.S. provides the lions share of funding for the intergovernmental military alliance, and that America has been ripped off by other NATO members, including Germany. He has also slammed NATO as being obsolete.

But Douglas Lute, a former U.S. ambassador to NATO under President Barack Obama, said no country technically owes the United States anything. Rather, each NATO member has its own military and own defense budget, and works with other signatories for the common defense.

He said most European nations dramatically reduced their military spending in the 1990 s with the breakup of the Soviet Union. That mindset only changed in 2014, in accordance with the Russian intrusion of Ukraine and the annexation of Crimea, and the self-described Islamic States declaration of a caliphate in Syria right on the border of NATO member Turkey.

Lute said a NATO summit that year forged the agreement in which every member agreed to spend at the least 2 percent of its GDP on defense by 2024.

NATO members are now increasing , no longer reducing, their military budgets. Last year, Germany spent 1.19 percent of its GDP on defense, falling short of the spending target.

The reality today is that NATO has not only stopped, but reversed the trend and is two-and-a-half years into a 10 -year plan, Lute said.
