Israel had two friends in the Middle East. The first was Hosni Mubark who had continued with the policy of Anwar Sadat of engaging Israel. The second was Turkey which has a secular constitution. But the world changed very fast as Hosni Mubarak was overthrown and put on trial. Secondly a hard line Islamic party came to power in Turkey which began to review the partnership with Israel. Both these develpments had wide ramifications.
The new dispensation in Egypt is not at all favorable to Israel. Mass demonstrations led by hard line Islamic militants laid seige to the Israeli embassy. TheIsraeli ambassador had to escape secretly and has not returned. The Turks attempted to run the blockade of Gaza and lost 15 men when the Israeli Navy fired on them.
The situation now is a real pot boiler. Iran has declared its intention to destrory Israel and Hamas that terrorist wing of the PLO is flexing muscles for a rocket attack on Israel. In such a scenario
Israel has already lost the initiative in the Middle East and the only way a status quo can be maintained is for Israel to strike at Iran. But that can only be with overt and covert support of the USA. President Obama is not inclined to get involved in another war in Iran with elections around the corner. Thus Israel is very much on its own and one will have to await and see which way the drama unfolds.
