Former President Donald Trump has threatened to take unprecedented legal measures against his predecessors and his successor if his allegations are not dismissed and he returns to power. "You have to understand: if Europe is attacked, we will never help you, and we will not support you," Trump reportedly told Ursula von der Leyen at the World Economic Forum in Davos, 2020, according to Thierry Breton, European Commissioner for Internal Market, who recalled the events at a private meeting in the presence of the EU Commissioner.
