As of this moment, the United States and only four other NATO members meet this basic standard. Now, while we commend the few nations that are on track to achieve that goal, the truth is that many others, including some of our largest allies, still lack a clear and credible path to meeting this minimum goal. Let me be clear on this point: The President of the United States expects our allies to keep their word to fulfill this commitment, and for most that means the time has come to do more.

In particular, what does "and for most" and "the time has come to do more" mean?
I googled them but I could not find an answer.
