Which world do you live in?
Russia from the beginning totally and utterly screwed this up.
A population of roughly 150million v a population in Ukraine of roughly 36million pre-war.
Russia's army was 1,320,000 pre-invasion. Ukraine's roughly 700,000.
Russia had 17,500 tanks, a significant proportion of which were unusable admittedly. Ukraine had around 700 iirc.
Russia has lost over 8000 tanks and FIFTEEN THOUSAND artillery systems.
They couldn't even get their 64km long army to Kyiv!
Putin claimed to take over Ukraine in 3 days. It's now 2 1/2 years on and they are reduced to primitive human meat waves to take village by village slowly, and they have taken only 20% of Ukraine.
Their elite units were wasted by bad generalship early in the war and while some of the surviving soldiers are battle hardened and good, most units are not cohesive due partly to the fact that training is poor, because the trainers were sent to the front lines too early in the war!
They've gone from the 2nd most feared army in the world to a laughing stock.
Im afraid that if you seriously think that Russia is better prepared then you'd better start looking at what's actually happened, rather than what you want to have happened.
