That's seems a massively selective pov with cherry picked hindsight used for confirmation bias. I recall many many more variables and that's only counting the ones we know.

We started this endeavor well past the invasion date. Its like a mfg that has been off-line for weeks, you simply dont turn power on and start rolling out 5000 widgets. so many things have to be in place.
But more importantly, perception. Specifically to Putin. He guessed right that the Western response would be ineffective/weak. And it was. Had the perception been that the West isnt playing, he has to go from "Special Military Operation" ( how he sold it domestically ) to "its a War" which has quite different connotations in Russia.
There are absolutely many aspects that arent accounted for, but perception of strength, in a battle, is a long standing tenet of war.
Our consistent delays were a hindrance to achieving a perception of a solid, unified block of countries that werent swayed by sabre rattling.
and i very well may be missing other aspects of "coalescing" support.
But its long been my opinion that our perception globally has been weakened over the last 15 years or so and that our will to do what is needed has eroded.
