美国总统特朗普炮轰完加拿大后，又连发推文，将目光转向欧洲。特朗普称，美国几乎支付了全部的北约军事费用，保护那些很多占我们便宜的国家。欧盟与美国有1,510亿美元的贸易顺差，应支出更多军事费用。德国向北约支付费用占其GDP的1%，而美国支出的份额为4%。“这合理吗？”
特朗普并指，美国为了保护欧盟（这很好）承受了巨大的经济损失，但美国却在贸易上得到不公平待遇。是时候改变了！
特朗普还说，为什么我，作为美国总统允许这些国家继续对美国巨额贸易顺差，它们这么干了几十年，而我们的农民，工人，纳税人却要为此付出这么巨大，不公平的代价。对美国人民不公平！一年8000亿美元的贸易赤字。

....Germany pays 1% (slowly) of GDP towards NATO, while we pay 4% of a MUCH larger GDP. Does anybody believe that makes sense? We protect Europe (which is good) at great financial loss, and then get unfairly clobbered on Trade. Change is coming!
....And add to that the fact that the U.S. pays close to the entire cost of NATO-protecting many of these same countries that rip us off on Trade(they pay only a fraction of the cost-and laugh!). The European Union had a $151 Billion Surplus-should pay much more for Military!
Why should I, as President of the United States, allow countries to continue to make Massive Trade Surpluses, as they have for decades, while our Farmers, Workers & Taxpayers have such a big and unfair price to pay? Not fair to the PEOPLE of America! $800 Billion Trade Deficit...

7国集团峰会（G7）已落幕，特朗普拒绝签署美国本已同意的7国集团联合声明，推翻峰会共识，并且猛烈抨击加拿大总理杜鲁多；指加拿大对美国征收270%的乳制品税，然后杜鲁多还假装受害者。美国首席经济顾问库德洛更指责加拿大在“背后捅刀子”。
德国总理默克尔形容特朗普会后的推文“令人沮丧”；承认下月在北约领袖会议上与特朗普的对话将会非常艰难。对于特朗普威胁向进口汽车征收关税，超过80万人从事汽车相关行业的德国或许会首当其冲，默克尔回应：“会考虑如何对应，希望这次欧盟会团结作出一致性行动。”
