Setting the tone for Wednesday's NATO summit in Brussels, Trump took to Twitter Tuesday to voice his displeasure with the US having to foot the bill after NATO countries failed to meet their two percent GDP defense budget obligations. Stating the move was "not fair to the US taxpayer," the US President did not have to wait long to get some kind of response.
"It is always worth knowing who is your strategic friend and who is your strategic problem," Tusk said, sending a warning to the Trump, who is also scheduled to meet with Russian President Vladimir Putin while overseas.
"Dear America, appreciate your allies. After all, you don't have that many. And dear Europe, spend more on your defense, because everybody expects an ally that is well-prepared and equipped."
Firing back before boarding his flight, the the US president remarked to reporters that his meeting with Putin "may be the easiest of all."
