Donald Trump was deliberately left in the dark about Ukraine’s unprecedented drone strike in Russia on Sunday, which destroyed nearly a third of the Kremlin’s strategic bomber fleet in a surprise attack.

The large-scale drone attack saw a fleet of drones scattered all across Russia carry out simultaneous attacks on five airbases, wiping out 40 irreplaceable military bombers worth an estimated $7 billion, which have been used to reign terror upon Ukrainian civilians.

“Operation Spider-Web” took over 18 months to plan and was personally overseen by Ukrainian President Volodymyr Zelensky, a source told CBS News.
