Zechariah 9: the humble King

The Jews came from exile. In this chapter, we read that the Lord will punish the surrounding nations, specially Tyre.
The Lord says that He will protect his people:

8 I will set up camp in my home country
    and defend it against invaders.
Nobody is going to hurt my people ever again.
    I’m keeping my eye on them.

The Lord will establish a king in Jerusalem:

9-10
“Shout and cheer, Daughter Zion!
    Raise your voice, Daughter Jerusalem!
Your king is coming!
    a good king who makes all things right,
    a humble king riding a donkey,
    a mere colt of a donkey.
I’ve had it with war—no more chariots in Ephraim,
    no more war horses in Jerusalem,
    no more swords and spears, bows and arrows.
He will offer peace to the nations,
    a peaceful rule worldwide,
    from the four winds to the seven seas.

Jesus took care to enter in Jerusalem riding a donkey and the crowd understood that He was the Messiah, this king that Zechariah prophesied.
Did Jesus offer peace to the nations? Was this prophecy fulfilled?
We Christians believe so, but it happened in a way that was very obscure to understand: Jesus was crucified, He resurrected, and through his disciples, He offered peace to the nations.
