The Shabbat after Tisha b'Av is called Shabbat of Consolation, or Shabbat Nachamu, because of the passage which is read from the Haftarah, the prophetic portion read each Shabbat right after the Torah portion.
This week's portion is from the prophet Yishayahu (Isaiah) comforting the people after the destruction of Jerusalem and the Beit HaMikdash:
It is a message of the future end of the long exile of the Jewish People and the rebuilding of our capital city, Jerusalem, as well as the Beit HaMikdash. This has already begun, in our day--with the miraculous return of Jewish sovereignty to the Land of Israel, and the subsequent re-building of Jerusalem.
Here is an interesting incident in recent past Jewish history which happened on Shabbat Nachamu, and relates to the inception of the State of Israel, written by my good friend Larry Domnitch, entitled A Message was Captured in Jerusalem One Shabbat Morning. Read it in it's entirety. It is a message of hope.
