I'm of the mind that Nato and EU were not so surprised about Putin entering Ukraine.....but were preparing for it for a few years and knew that Zelensky would stand...and that Biden (former Obama administration) would be in office. When considering all the troops and drills and armament that's been flowing into Nato nations bordering Russia .....and increasingly so over the past few years.....Putin has seen all this...and they knew he would.
Further the fact the G-7 kept brushing off negotiating for security agreements.....I can't say they all didn't know and were preparing for this.
Therefore what you said makes sense.
