It would be hard to resist compulsive tweeting if even your typos attract worldwide attention. Donald Trump's "negative press covfefe" received as much covfefe this week as his announcement withdrawing the US from the Paris Agreement on climate change.
Perhaps that was appropriate, his stumbling thumb was a fair reflection of the mess he is making of United States foreign policy.
On trade, collective security and now climate change he has relinquished the position of leadership the US has sought or accepted for the past century.
He is doing no more or less than he promised before his election, so it will do him no harm. But even his supporters, surely, would wish he gave up twitter.
He (or a minder) managed to control his thumb during his first presidential visit to foreign capitals last week but once back in the White House he could not resist.
