The situation in the Gaza Strip is unlikely to witness any positive changes. Even if Hamas were to be removed from power, the Palestinians would continue to suffer under other radical groups such as Palestinian Islamic Jihad (PIJ).
Even if Hamas were to wake up tomorrow morning and have an about-face, striking a genuine truce with Israel, there will always be other terrorist groups that are prepared to breach the agreement any time they wish.
These are crucial factors that need to be taken into account by any international party that seeks a solution to the catastrophe called Gaza. Alternatively, one might to wish to continue to inhabit some alternate reality in which all be would be well if Israel would only ease restrictions on the Gaza Strip.
