Everyone else sees very clearly that an alliance which only invokes when attacked and requires the resolution of territorial disputes prior to gaining membership is not going to just invade them first.
Half of the members were literally dependent on Russia for their energy needs, many of them thinking that the US was the warmongerer for being constantly paranoid about Russia's intentions, with defense budgets trending downwards and the former American president having openly questioned the need for NATO. There is no reasonable way to argue that they were at all going to be attacking Russia as an alliance in that state.
