Think of the jihad in terms of the pirates that plied their murderous trade on the high seas during the 16 and 17th centuries. They all were pirates, loosely affiliated, with roughly the very same goals (self enrichment at others expense) and sailed under the same flag, or something that was strikingly similar. It matters little what the group calls itself, but what its chief aims are.
Al-Qaida, Hizb ut-Tahrir or the Muslim Brotherhood, no matter how they carry out their agenda in attacking the West, it’s their goals that matter most, the subjugation of the west and installtion of the world caliphate. Those who follow the TT regularly, know that the stealth jihad is the most important and dangerous aspect of the jihad(s), the violent and stealth version. Robert Spencer wrote an excellent book about it. It’s the stealth jihad that has been the more successful of the two jihads, and have made deep enrodes not only into Muslim communities in the west, but in key government institutions as well.

Muslim Brotherhood Declares War on America; Will America Notice?
By Barry Rubin

This is one of those obscure  Middle East events of the utmost significance that is ignored by the Western mass media, especially because they happen in Arabic, not English; by Western governments, because they don’t fit their policies; and by experts, because they don’t mesh with their preconceptions.

This explicit formulation of a revolutionary program makes it a game-changer. It should be read by every Western decisionmaker and have a direct effect on policy because this development may affect people’s lives in every Western country.

OK, cnough of a build-up? Well, it isn’t exaggerated. So don’t think the next sentence is an anticlimax. Here we go: The leader of the Muslim Brotherhood has endorsed (Arabic)(English translation by MEMRI) anti-American Jihad and pretty much every element in the al-Qaida ideology book. Since the Brotherhood is the main opposition force in Egypt and Jordan as well as the most powerful group, both politically and religiously, in the Muslim communities of Europe and North America this is pretty serious stuff. 
By the way, no one can argue that he merely represents old, tired policies of the distant past because the supreme guide who said these things was elected just a few months ago. His position reflects current thinking.
Does that mean the Egyptian, Jordanian, and all the camouflaged Muslim Brotherhood fronts in Europe and North America are going to launch terrorism as one of their affiliates, Hamas, has long done? No. 
But it does mean that something awaited for decades has happened: the Muslim Brotherhood is ready to move from the era of propaganda and base-building to one of revolutionary action. At least, its hundreds of thousands of followers are being given that signal. Some of them will engage in terrorist violence as individuals or forming splinter groups; others will redouble their efforts to seize control of their countries and turn them into safe areas for terrorists and instruments for war on the West.
When the extreme and arguably marginal British Muslim cleric Anjem Choudary says that Islam will conquer the West and raise its flag over the White House, that can be treated as wild rhetoric. His remark is getting lots of attention because he said it in English in an interview with CNN. Who cares what he says?
But when the leader of the Muslim Brotherhood says the same thing in Arabic, that’s a program for action, a call to arms for hundreds of thousands of people, and a national security threat to every Western country.
The Brotherhood is the group that often dominates Muslim communities in the West and runs mosques. Its cadre control front groups that are often recognized by Western democratic governments and media as authoritative. Government officials in many countries meet with these groups, ask them to be advisers for counter-terrorist strategies and national policies, and even fund them.
