The Assembly of Muslim Jurists of America (AMJA) opposes offensive jihad in the West, but for reasons that may surprise you. In an Arabic fatwa (religious decree) that doesn't appear on its English website, it states that "the Islamic community does not possess the strength to engage in offensive jihad at this time [emphasis added]."
This doesn't mean that all jihad is to be abandoned. "With our current capabilities, we are aspiring towards defensive jihad, and to improve our position with regards to jurisprudence at this stage. But there is a different discussion for each situation," it said.
It is important to notice that it was issued in Arabic on the website of its Secretary-General, Salah Al-Sawy. Even though AMJA is based in Sacramento and its mission is to serve their American Muslim audience, it decided against issuing this fatwa in English. If it wasn't translated by the Translating Jihad blog and reported by Andrew Bostom in 2011, we probably wouldn't know about it.
