Trump’s not the first US president to fall in love with war. History shows where this is going | Peter Beinhart

In his fresh intoxication with global conquest, Trump is following an established pattern - one that promises disaster

To many observers, Donald Trump's open bellicosity - his threats to attack Greenland and Iran, and his recent kidnapping of Venezuela's president, Nicolas Maduro - looks like an ideological reversal. Donald Trump betrayed his MAGA base today [by] launching a war of choice to bring regime change in Venezuela," tweeted Democratic congressman Ro Khanna on 3 January. The day before, former Republican representative Marjorie Taylor Greene wrote: President Trump threatening war and sending in troops to Iran is everything we voted against in 24." On 20 January, National Public Radio reported that Trump supporters share confusion and anger over the president's focus on Greenland".

The sense of whiplash is understandable. As a candidate, Trump often denounced war. Now he is infatuated with it. But while Trump seems uniquely set on dismantling the postwar order in the service of his quest for global domination, there is precedent for his transformation.
