Released terrorist vows to do whatever it takes to get Israel to release more terrorists

Yesterday, I noted that one of the released terrorists was Yehye al-Sinwar, who had tried to orchestrate a Shalit-style kidnapping while in Israeli prison.

Today, at the Gaza border, he congratulated the terror groups that were involved in Shalit's kidnapping and he vowed  that Hamas would do whatever it takes to get the remainder of Arab terrorists released from prison, "at all costs."

What do you think he means by that?

Somehow, I don't think it means recognizing Israel and accepting peace.
