At the moment, nothing shouts "Policy Change!" like the way the current Egyptian government has been handling the Gaza crisis. During the Israeli assault on the Gaza Strip in 2012, Morsi managed to broker a ceasefire within one week from the start the Israeli offensive. Today marks day 7 in the current Israeli offensive, and there has been no news of any mediation that has arrived to anything substantial.
During the 2012 Israeli offensive, the Rafah crossing, a vital lifeline for Gaza to the outside world, was open around the clock, and all holidays for Egyptian employees at the crossing were cancelled. During the current Israeli operation, the crossing has been closed, opened, and closed again.
Morsi had made public statements denouncing the Israeli assault against the Palestinians. Sisi, on the other hand, has taken a more neutral approach. Statements by presidential spokesmen and government officials relay to the public Sisi's 'concern' regarding possible escalations that may occur in the crisis.
The two foreign policies also contrast on the issue of Syria. In mid-June, 2013, just weeks before Sisi overthrew Morsi, the latter had announced that Egypt would cut all ties with Assad's regime. He announced that decision during a pro-Syrian-revolution conference that was broadcast on live television. Sisi, so far, has called for a peaceful solution to the conflict and has stated that Syria is becoming an "attractive spot for terrorism."
It is clear and evident that Sisi is taking Egypt on a different foreign policy that contrasts greatly with his predecessor. The current Israeli offensive against Gaza will definitely test how successful his policy will be.
