The senior official said that EU should be grateful to Trump as he helped the bloc get rid of its illusions.
Previously in March Tusk offered a more conciliatory stance on the economic differences between the US and EU, urging Trump to "go back" to trade talks instead of waging a "trade war."
President of the European Commission Jean-Claude Juncker also remarked last week that the European Union should replace the United States as a global leader after the latter "as an international actor has lost vigor, and because of it, in the long term, influence."
Earlier this month, US President Donald Trump announced that his country would exit the 2015 nuclear deal, formally known as the Joint Comprehensive Plan of Action (JCPOA), and reinstate the previously lifted sanctions on Iran. Other signatories to the JCPOA have criticized Trump’s decision to unilaterally pull out the deal.
