>NATO expands because it's in NATO's interest to do so.
I highly recommend reading the 1997 US Senate debate about NATO expansion. There were a number of experienced statesmen who vehemently disagreed that NATO expansion was in NATO's interest.
> A world of where rule of law is the norm and invasions are deterred is preferable.
Except we don't have that world. From Iraq in 2003 to especially the NATO air campaign in Libya in 2011, we've long since demonstrated that there are no rules, and invasions have no consequences.
