After the events of today, surely the only question any reasonable person will be asking is, how long before the Americans get a grip and throw Trump out. Before today, the notion that they could do so has always seemed vaguely fanciful, but after Trump’s embarrassing performance in Helsinki today, surely it is becoming a realistic prospect. How could any self-respecting nation bear to be shown up by such an egotistical moron, willing to discredit his own intelligence services for his own self interest? Even Republicans are denouncing Trump for his behaviour today. In all seriousness, it can now be only a matter of time – weeks, I suspect – before America finds a way of replacing Trump with someone more qualified.
