Trump asked how much the new NATO headquarters cost--Google will tell you. Then he said NATO countries owed lots of money. NATO is not a golf club where you pay green fees. The assembled audience grumbled and snickered at the President of the United States.
FYI--Under President Obama, NATO nations made commitments to raise their defense budgets and reach the desired goals by 2020.
So we have a trip where the President of the United States admitted he leaked classified info from Israel. Leaked the name of the Manchester bomber. Now Israel and the UK is withholding intel from the United States. And we finish this leg of the tour insulting a real allies.
