Robert Habeck says world has moved on from weaponising energy to using tariffs, technology and more to inflict harm

The weaponisation of energy when Russia invaded Ukraine has given way to “weaponising everything” since Donald Trump returned to the White House, Germany’s former economy minister has said.

Robert Habeck, the Green politician responsible for keeping the lights on during the last energy crisis, said the belief gas “would never be a political weapon” led successive German governments blindly into Putin’s trap by building the Nord Stream pipelines and selling strategic reserves to Gazprom, which Russia emptied before the invasion.

But the re-election of Donald Trump led to a second security shock with “dramatic, drastic … and far-reaching” consequences which include using tariffs and technology as weapons, he told the Guardian.
