He who pays the piper calls the time.

 Never has this well known expression been more appropriate. Trump has said many times that NATO members must spend more on their collective defence in future. The US has for too long - done the heavy lifting on defence in Europe. So reluctantly they have agreed to up current spending to at least 5% of GDP in the next decade. Trump can rightly claim a victory in this regard - as all member countries have been hiding behind the - American largesse and generosity. It’s long been a serious political problem between the US and NATO countries, but hitherto nothing had changed. So in The Hague today in Holland history was at long last made. He who pays the piper calls the tune.
