The US president has issued a blizzard of edicts and announcements. Determining where to focus the fightback will be difficult but essential

Waiting for Donald Trump’s inauguration on Monday was like watching a tsunami gather force. Everyone could see the threat approaching. But its scale was still shocking as it hit land, and what damage it wreaks will ultimately take months and years to determine.

The deluge is intentional. For supporters, there is a sense of unleashed macho, almost messianic energy – setting the US on a path to national destiny which might take in Greenland, Panama and ultimately Mars. This time Mr Trump has an electoral mandate, a compliant team with a ready agenda, the obsequiousness of billionaires who command the attention economy, and a compliant supreme court which has already granted the president extraordinary power. He aspires to the rule of a monarch. The flood of executive orders, pardons and pronouncements is intended to overwhelm and intimidate, but also to disorientate opponents.
