Trump 2.0 would mean chaos and threat for Europe. Now is our chance to prepare | Nathalie Tocci

If you thought his first term was bad, brace for a White House that abandons Ukraine, emboldens Putin and encourages the far right

As Donald Trump romps to the Republican nomination for the next presidential race, there is justified anxiety among the US's European allies about his return to the White House. It is all but certain that 2024 will see a rerun of Joe Biden v Trump. Europe needs to prepare for the possibility of a second Trump presidency.

The last one was traumatic for Europe. This was not really for policy reasons. There were policy divisions such as Trump's withdrawal from the Iran nuclear deal. But transatlantic policy tensions are hardly new: there have been times - the US-led war in Iraq in 2003 for example - when the rift was deeper.
