Excellent move. New entrants should be required to show that they bring something to the table. A minimum of 200 4th generation fighter aircraft would be a good start, combined with at least 250 tanks and 1000 armored vehicles each. Too many new NATO members have been welfare cases.
Is not NATO an anachronism, a relic of a past that is no longer relevant?
An overinflated balloon is easily popped.
I think they jumped the shark in Libya.
But healthy criticism of what NATO has become is another thing, It should be fixed immediately, starting from things like “spend at least 2.5% of GDP on the military or f. out”, there are countries in it, which are totally not interested in defense issues, such as Belgium and others, which follow “either America helps us or we're doomed anyway” logic like majority of post cold war new member states. So in result NATO is a totally impotent and ineffective political club, UN 2.0. It must be fixed immediately or shut down - better that than giving false security guarantees.
