How Iran Plans to Take Gaza

 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.
…If anyone was hoping that removing Hamas from power in the Gaza Strip would improve the situation there and boost the chances of peace between Palestinians and Israel, they are in for a big disappointment. Hamas, which violently seized control over the Gaza Strip in the summer of 2007, is not the only terrorist group in the coastal enclave, home to some two million Palestinians.
In addition to Hamas, these are several other Palestinian terrorist groups in the Gaza Strip.
The second-largest group after Hamas is Palestinian Islamic Jihad (PIJ), which has thousands of supporters and militiamen. If and when Hamas is ever removed from power, PIJ has the strongest chance of stepping in to fill the vacuum.(by gatestonesinstitute.org).
