So 9 countries most people could not even point to on a map
Also EVERY NATO nation needs to agree to a nation joining, if even one says nay then a nation cannot join NATO
Also in order for a nation to join NATO you cannot have any disputed borders or any border issues
Lastly have any of these nations given any money or supplies to Ukraine? Oh wait that’s right, they just wait for America or France or UK or Germany to bear the burden
Every single one of those countries has given weapons and money to Ukraine, commensurate with—and sometimes above—their abilities Poland ranks 3rd behind the U.S. and UK in aid to Ukraine - Germany has given jack by comparison. Slovakia sent its only S-300 air defense missile system and the other countries have sent tanks, artillery, and a sh#t ton of ammunition, just to name a few. Lithuania had been sending weapons and ammo for years - well before the U.S. sent its first Javelin.
Also, while it is true that all Allies must agree to admit a new member (looking at YOU, Hungary and Turkey), there is no rule about borders. However, many NATO members would want to be reassured they would not be dragged into some longstanding conflict.
