Vladimir Putin threatens nuclear war if the West sends troops to Ukraine. This is not the first time since the outbreak of the invasion two years ago that the Russian president has raised this supreme threat.

As proof, a person familiar with the matter points out that deep Ukrainian strikes, using Western weapons, destroyed strategic fuel depots, more than 1000 km inside the Russian border. “It was unimaginable two. years ago, delivering such means constituted a red line,” insists this source.
