Following President Abdel Fattah al-Sisi's takeover of Egypt, Hamas only recently made some progress in burying the hatchet with Cairo; in the past few weeks Egypt has opened the Rafah crossing between Egypt and Gaza for long stretches and allowed people and goods to pass in and out of the choked Gaza Strip. The conventional wisdom is that the relationship between Egypt and the Palestinian militant group will again deteriorate. There have even been reports in Israeli newspapers linking Hamas with Wilayat Sinai, hinting that the two sides have cooperated by sharing weapons. However, given the differences between the two groups, Stratfor is skeptical that they would coordinate efforts. Hamas is fundamentally an organization bent on the realization of an independent Palestinian state; its ideology is incompatible with the Islamic State's universal aspirations to achieve a global caliphate.
