How is the west being arrogant if the new member states want to join? It's not the west who invaded Georgia in 2008 or Crimea in 2014. It's not the west that invaded Ukraine in 2022. Countries bordering Russia have, for decades, known the threat that Russian imperialism is to them and it's their choice to protect themselves from an extremely aggressive, brutal neighbour.
Never understood people who believe the narrative of an expanding NATO. The baltics, Poland and other Eastern countries want to join NATO because they have been invaded several times by Russia, women raped, cities plundered, people tortured and killed. That is the reason those countries want to join NATO.
