Here is an excerpt from an Israel National News article:
The friendliness of U.S. President Barack Obama toward the Muslim Brotherhood, a movement formerly considered illegitimate by the West, is now seen as one of the reasons for Mubarak’s downfall and the Brotherhood’s rise to power.
Israelis are now concerned that Egypt may cease to honor its treaty with Israel, and that terror from Sinai and Gaza will increase. An even more worrisome scenario would involve the remilitarization of the Sinai, which serves as a buffer zone between Israel and Egypt.
They did not beat around the bush. They made it clear that Obama was one of the main reasons for the rise to power by the Muslim Brotherhood.
Israeli PM Benjamin Netanyahu accepts the results of the democratic election and believes they can work with Egypt.
"Israel appreciates the democratic process in Egypt and respects its results,"
"Israel expects the continuation of the cooperation with the Egyptian regime on the basis of the peace treaty between the two countries, which is an interest of both peoples and contributes to the stability of the region."
