 He believes that the longer he waits, there'll be more pressure on Israel to agree not just to a temporary ceasefire, but to a permanent ceasefire and a total withdrawal from the Gaza Strip. Hamas wins. Game over. Oren says Hamas also hopes delayed U.S. arms shipments to Israel will help it force the Jewish state into a permanent ceasefire and a withdrawal from Gaza. Now, what really makes no sense to me is that the only way to get Hamas to agree to a ceasefire is by increasing the military pressure on Israel.
