"Someone could even think 'with friends like that, who needs enemies?'" reads the tweet from EU Council president Tusk - adding, "thanks to him (Trump), we got rid of all illusions".
Tusk, a long-time critic of Trump, said the European Union needed to be united to face "a new phenomenon - the capricious assertiveness of the American administration".
With member states yet to agree on how to handle the challenges, Mr Tusk called on leaders gathering in the Bulgarian capital, Sofia, to unite behind the tough line being taken by key European actors in response to the White House's actions. Donald Tusk told reporters ahead the EU leaders' agenda dinner for the EU-Western Balkans summit set for Thursday in Sofia, Bulgaria. To the dismay of European Union leaders, Trump also pulled out of the Paris climate accords, moved the US embassy in Israel to Jerusalem, and imposed unilateral tariffs on steel against some trading partners. "But at the same time, we must be prepared for those scenarios, where we will have to act on our own", said Tusk, a former Polish prime minister.
European Council President Donald Tusk lashed out at the USA president, blasting his decision to pull out from the Iranian nuclear deal and stirring up trade disputes with other countries, and lamenting that one does not need enemies with friends like Trump. "That means permanent exemptions from USA tariffs on aluminium and steel".
"I have no doubt that in the new global game, Europe will either be one of the major players, or a pawn". This is the only real alternative.

That's the same firm Cohen used to pay adult film star Stormy Daniels to keep quiet about her alleged affair with Trump. Ehrat said Wednesday that he would retire, because of the role he played in setting up the contract.
Mr Tusk said the U.S. appeared to be hesitating in hitting European companies doing business in Iran with sanctions, but the bloc still needed to be ready to protect its interests.
Tusk also demanded that Trump grant a permanent exemption to the European Union from threatened tariffs on steel and aluminum, and he rejected as "absurd" any assertion by the that such tariffs could be justified on national security grounds.
The EU has called for "utmost restraint" after Israeli forces killed 60 Palestinians during clashes and protests along the Gaza border against the opening of the U.S. embassy in Jerusalem, the conflict's bloodiest day in years. The shifting desires make it almost impossible to negotiate with the White House, many diplomats say, because they can not strike a bargain to get close to what Trump wants when he doesn't know it himself. "We need to bring reality back into this discussion".
