How did a former security officer get it so so wrong ???
16min 20 - putin overconfidance in military - plus weak European reaction to Crimea / Donbas
(timetables given to soldiers were that they would get into Kyiv between 3 pm and midnight on first day .)

sychophancy and fear had robbed putin of independant wise advice
23 min institutional russian military rot ! Everyone in the military knew - but not ptin .
25 min Ukraine sent spies into russia - they quickly worked out an attack was coming - and that logistical support for it was inadequate
25min 30 --- the five points that brought the russian attack undone
Naryshkin (director of foreign intel) was the only advisor to sound a note of caution ,(no-one else dared ) , putin hammered him and he quickly agreed (sensibly)

basically - putins own autocratic system he created to cement himself in power that was the main reason for putin not getting the good advice he needed
