 Before flying to Brussels where he arrived on Tuesday night, Trump again chided fellow NATO members for not contributing enough while maintaining a trade surplus with the United States, his latest reprimand on issues that are straining transatlantic relations. 
  
 “Dear America, appreciate your allies, after all you don’t have that many,” Tusk, a former Polish prime minister, said after a signing statement on more cooperation between the European Union and the North Atlantic Treaty Organisation. 
  
 As European Council president, Tusk serves as the chairman when EU leaders meet at summits. 
  
 Even while in the air, Trump kept up the attack. He said in a Twitter post that a trade deficit with the European Union “makes it impossible for our farmers and workers and companies to do business in Europe ... and then they want us to happily defend them through NATO, and nicely pay for it. Just doesn’t work!” 
  
 The European Union is the top export market for the United States at $501 billion in goods and services in 2016, the latest available figures provided by the Office of the U.S. Trade Representative. Imports totaled $592 billion, leading to a $92 billion goods and services trade deficit with the EU, according to the trade office’s data. 
  
 Back in Washington, the top Republican in the U.S. Senate, Mitch McConnell, told reporters he was not worried that Trump would withdraw the United States from NATO. McConnell also said “there is nothing inherently wrong” about Trump meeting with Russian President Vladimir Putin while he is in Europe. 
  
 Many U.S. presidents have urged European governments to spend more on their militaries. But Trump’s demands have been intensified and blunt to an extent that allies worry it could damage NATO morale and play into the hands of Putin, whom they accuse of trying to destabilize the West. 
  
 “Dear President Trump: America does not have, and will not have a better ally than Europe,” said Tusk. “Today, Europeans (collectively) spend on defense many times more than Russia, and as much as China.” 
  
 He said that money helped boost U.S. security, as the United States regards Russia and China as threats. 
  
 NATO released new estimates for allied defense spending in 2018 on Tuesday, showing that Latvia and Lithuania are set to meet the target of spending 2 percent of economic output on the military. Of the 29 allies, only the United States, Britain, Estonia, Greece and Poland met the goal in 2017. Romania is also on course to hit it in 2018, NATO said. 
  
 NATO Secretary-General Jens Stoltenberg stressed that all allies were increasing defense spending in real terms because economies in Europe were growing. He also said Washington strengthens its security and global reach through NATO. 
  
 Trump’s Twitter post on Tuesday echoed those on Monday and his criticism at a rally of supporters in the United States last week in which he said that Washington was unfairly carrying almost all the cost of defending Europe. 
  
 “Getting ready to leave for Europe. First meeting - NATO. The U.S. is spending many times more than any other country in order to protect them. Not fair to the U.S. taxpayer,” Trump said. 
  
 As he left the White House, the Republican president was asked by reporters about Tusk’s comments. 
  
 “We do have a lot of allies, but we cannot be taken advantage of. We’re being taken advantage of by the European Union,” he told reporters. 
  
 European officials say while U.S. defense spending makes up 70 percent of combined allied governments’ military budgets, just 15 percent of U.S. expenditure is spent in Europe on NATO-related defense. Washington pays about 22 percent of the running cost of NATO, including the headquarters and commonly-funded equipment such as AWACS surveillance planes. ||||| Getting ready to leave for Europe.

 President Donald Trump predicted Tuesday that his upcoming summit with Russian President Vladimir Putin “may be the easiest” of the meetings he has scheduled for his weeklong trip to Europe. 
  
 The president departed Tuesday for his trip, which will take him first to Brussels, where he will attend the NATO summit on Wednesday and Thursday. From there, Trump will travel to the United Kingdom, the government of which has been roiled in recent days by the resignation of top Cabinet officials, for bilateral meetings.

 Trump will meet with Putin next Monday in Helsinki. 
  
 “So I have NATO, I have the U.K., which is in somewhat turmoil, and I have Putin. Frankly, Putin may be the easiest of them all. Who would think? Who would think?” Trump told reporters as he departed the White House Tuesday morning. “But the U.K. certainly has a — they have a lot of things going on.”

 Trump has faced significant scrutiny for his willingness to meet with Putin amid an ongoing investigation into Russia’s interference in the 2016 U.S. presidential election and allegations that the Trump campaign colluded in those efforts. The president has insisted that there was no collusion and that the investigation is a “witch hunt.” 
  
 The Russian government, and Putin himself, have steadfastly denied any efforts to interfere in the 2016 election, a denial that Trump has at times seemed hesitant to reject even though the U.S. intelligence community has been unanimous in its conclusion that the Kremlin was behind the interference efforts. 
  
 With NATO meetings upcoming on Wednesday and Thursday, Trump has renewed his criticisms of the treaty organization, chiefly that its member states do not spend enough on defense, leaving the U.S. to carry too much of the mutual-defense burden. He wrote on Twitter Tuesday that “NATO countries must pay MORE” and “the United States must pay LESS.” 
  
 Trump has complained loudly that just a handful of nations spend the agreed-upon 2 percent of their gross domestic product on defense. NATO Secretary General Jens Stoltenberg has been public in agreeing with Trump and wrote in a Wall Street Journal op-ed that eight of NATO’s 28 member states are expected to meet the 2 percent threshold this year, with a majority on track to do so by 2024. |||||

President Trump is leaving for his NATO summit in Brussels on Tuesday morning in an apparent good mood—and happy to take some preemptive shots at the world bloc. "Thank you to all of my great supporters, really big progress being made," Trump tweeted. "Economy is ROARING. Supreme Court pick getting GREAT REVIEWS. New Poll says Trump, at over 90%, is the most popular Republican in history of the Party. Wow!" And in multiple tweets, he reiterated a familiar theme, complaining that the US is shouldering an unfair share of defense costs overseas: "NATO countries must pay MORE, the United States must pay LESS," he tweeted. "Very Unfair!" The sentiment already isn't playing well, with European Union President Donald Tusk firing off a zinger off his own Tuesday: “Dear America, appreciate your allies, after all you don’t have that many,” he said after a signing a cooperation pact between the EU and NATO, per Reuters. Trump will attend the NATO summit Wednesday and Thursday, with defense spending expected to be the toughest topic, reports CNBC. Then's he's off to Britain, Scotland, and finally to Finland for another high-profile summit on Monday—with Russian President Vladimir Putin. "So I have NATO, I have the UK, which is in somewhat turmoil, and I have Putin," Trump told reporters Tuesday, reports Politico. "Frankly, Putin may be the easiest of them all. Who would think? Who would think?"
