An audacious Ukrainian drone attack against multiple airbases across Russia is a humiliating security breach for Vladimir Putin that will doubtless trigger a furious response.
Pro-Kremlin bloggers have described the drone assault – which Ukrainian security sources said hit more than 40 Russian warplanes – as “Russia’s Pearl Harbor” in reference to the Japanese attack against the US in 1941 that prompted Washington to enter the Second World War.

The Ukrainian operation – which used small drones smuggled into Russia, hidden in mobile sheds and launched off the back of trucks – also demonstrated how technology and imagination have transformed the battlefield, enabling Ukraine to seriously hurt its far more powerful opponent.
Moscow will have to retaliate, with speculation already appearing online about whether President Putin will again threaten the use of nuclear weapons.
“We hope that the response will be the same as the US response to the attack on their Pearl Harbor or even harsher,” military blogger Roman Alekhin wrote on his Telegram channel.
Codenamed ‘Spider’s Web’, the mission on Sunday was the culmination of one and a half years of planning, according to a security source.

In that time, Ukraine’s secret service smuggled first-person view (FPV) drones into Russia, sources with knowledge of the operation said.
Flat-pack, garden-office style sheds were also secretly transported into the country.
The oblong sheds were then built and drones were hidden inside, before the containers were put on the back of trucks and driven to within range of their respective targets.
At a chosen time, doors on the roofs of the huts were opened remotely and the drones were flown out. Each was armed with a bomb that was flown into the airfields, with videos released by the security service that purportedly showed them blasting into Russian aircraft.

Among the targets were Tu-95 and Tu-22 bomber aircraft that can launch cruise missiles, according to the Ukrainian side. An A-50 airborne early warning aircraft was also allegedly hit. This is a valuable platform that is used to command and control operations.
The use of such simple technology to destroy multi-million-pound aircraft will be watched with concern by governments around the world.
Suddenly, every single military base, airfield and warship will appear that little bit more vulnerable if any truck nearby could be loaded with killer drones.

The most immediate focus, though, will be on how Mr Putin responds.
Previous attacks by Ukraine inside Russia have triggered retaliatory strikes and increasingly threatening rhetoric from the Kremlin.
But this latest operation is one of the biggest and most significant, and comes on the eve of a new round of peace talks between Moscow and Kyiv that are meant to take place in Turkey. It is not clear if that will still happen.
US President Donald Trump has been pushing for the two sides to make peace but Russia has only escalated its war.
Ukraine clearly felt it had nothing to lose but to also go on the attack.
