From an excellent article in English on the Spiegel Magazine site from Germany.

Islamism has attacked Israel from both the south and the north and Israel has no choice but to react. But there is more to it than that. Israel's military operation is important for the entire Western world. Until 2005, Islamism was able to successfully mislead the West into thinking that the "occupation" of Gaza and southern Lebanon was the cause of the terror attacks carried out against Israel. Now we know better: Islamism isn't out to change Israeli policy in the region, Islamism is out to completely eradicate the country of Israel. The same strategy is being used on a larger scale: The Middle East conflict is not the cause of Tehran's conflict with Western secularism. It is merely a convenient alibi.

Which kind of puts the lie to CarolC's mantra about the "occupation."
