Far be it from him to take the get out of jail free card that is a hugely distracting global crisis and instead try to use said crisis to remind people he is a complete and utter tit.
Though there are rumblings, Putin did Johnson a
biiiig favour in that, just before the invasion, there were very serious questions about his
competence as PM which, for most previous PMs would have probably triggered their honourable resignation over the matter. Except that Boris is a
greater lesser man than any of those and was dodging that particular bullet.
As a great admirer and student of Churchill (who had his own issues but, I feel, would have probably gone the route of re-establishing himself rather than hanging on by his fingertips when it was just his own butt on the line) I imagine he's relishing his wartime-leader possibilities (see also the Thatcher-bounce, post-Falklands, but not Eden/Suez, etc) but, perhaps gratifyingly, it seems he knows/fears the limits of direct national confrontation.
And his team in government are being roundly and rightly condemned for continuing the general counter-humanitarian policies that is their signature staple approach, even as the public has been stepping up to the plate (admittedly because they are perceived as more 'our kind of refugees' than all those other refugees that there has been an ambivalent split of attitude to, in recent years).
It's going to be awkward when there's no more potential "we're just waiting for the (next) report, it would be precipitous to act before the (latest) investigation is fully concluded", and it definitely helps that there's Ukraine 'happening'. But at some point there must be an impression that "there has always been war in Ukraine" (assuming it doesn't resolve/escalate somehow) and even if there isn't a reckoning for being entirely hypocritical (if not in the above case, probably something new, or newly rediscovered, because it's his general bumbling manner - with or without a logic of steel behind some of them - that bounces around and does that sort of thing that variously endears/deplores people of him at pretty much every point of his political(/journalistic) career, so far.
But Vlad did Boris a solid, definitely. There's a good chance even
he might have been toppled by the back-bench Tories who (either truly, or acting to 'support' their constituency views.... or being machiovellian for their own purposes) continued to put on the pressure.
