The Gaza war has at least one clear beneficiary, writes Marc Lynch:
Ayman al-Zawahiri has finally weighed in on behalf of al-Qaeda over the Gaza crisis, calling it part of the West's war on Islam and calling on Muslims everywhere to attack Western and Israeli targets. He sounds about as happy as I can remember hearing him of late. He probably can't believe his luck.
Israel's assault on Gaza has really created an almost unbelievable no-lose situation for al-Qaeda. If Hamas "wins", then al-Qaeda gets to share in the benefits of the political losses incurred by its Western and Arab enemies (Zawahiri mentions Mubarak and the Saudis in this tape, but not the Jordanians) and can try to take advantage of the political upheavals which could follow. If Hamas "loses", al-Qaeda still wins. It will shed no tears at seeing one of its bitterest and most dangerous rivals take a beating at Israel's hands or losing control of a government that they have consistently decried as illegitimate and misguided. Either way, the Gaza crisis guarantees that a far more radicalized Islamic world will face the incoming Obama administration—potentially severely blunting the challenge which al-Qaeda clearly felt after the election (hence Zawahiri's attempt to pre-emptively discredit Obama by declaring the attack Obama's "gift" to Muslims).
You should read the whole post. It goes well beyond the familiar observation that Israel's attacks have radicalized Arab opinion, zeroing in on how they've affected intra-Islamist rivalries. E.g.:
The way this crisis is playing out shows the bankruptcy and strategic dangers of trying to simply reduce Hamas to part of an undifferentiated "global terrorist front". The Muslim Brotherhood, from whence Hamas evolved twenty years ago, is no friend of the United States or Israel but is nevertheless one of al-Qaeda's fiercest rivals….Al-Qaeda has long been desperate for a foothold in Palestine, but has been largely kept out because Hamas has the place locked. Jihadist forums bear a deep grudge over Hamas's crackdown on various jihadist groups which have tried to set up shop there (Jaysh al-Islam, et al)….
Even if Hamas emerges weakened, as Israeli strategists hope, all the better (from al-Qaeda's point of view, that is). In general, where the MB is strong (Egypt, Jordan, and Palestine for example), AQ has had a hard time finding a point of entry despite serious efforts to do so, while where the MB is weak (Iraq, Saudi Arabia, Algeria, Lebanon) it has had more success. Up to now, AQ-minded groups have had little success in penetrating Gaza, because Hamas had it locked. Now they clearly have high hopes of finding an entree with a radicalized, devastated population and a weakened Hamas.
