In this case I think with regards to #1 and #3 again I point to the Ukraine war and how the NATO axis realy believes their actual superiority shit, they actualy believe they'll just march and the enemy will just run away in fear, that their toys are invincible etc.
I think the difference is that NATO has never had to go peer-to-peer against an enemy that could fight back so that's why it was so arrogant. The IDF has a recentish memory of going into Lebanon and getting it's shit pushed in, so it probably has a more sober assessment.
