Which actually isn't all that hard to explain. The Muslim part of the world has been the whipping boy of the West for quite some time now. Between the coup in Iran, funding Iraq (a secular state) to attack Iran (a muslim state), the 6 days war against Egypt for not toeing the line, two centuries of fiasco in Afghanistan, a decade of aggression in Iraq, the raid on Syria based on Mossad disinformation, and Israel acting like an aggressive prick and bombing neighbours left and right, yeah, you get the idea. And while Christian fundies may have a reason to cheer at that even if they don't actually like Jews, because their Rapture depends on Israel, the Muslims have no such reason to cheer.
Add belligerent speeches by idiot fundies, including Dubya apparently acting under orders from God, and it starts to sound even to a lot of non-Muslims like the new crusades.
But it's not just that they have reason to hate the Christian West.
Remember that part about all those bellicose-sounding Suras being in the context of an armed attack at the time on the Islam? Bingo. That's why they can be used against the West right now. Not as much just because it's that freely interpretable, but because it's trivial to present it as the same kind of war on the Islam that the polytheists of Mecca were doing at the time. You don't actually need to reinterpret much. Once you have a bunch of people convinced there's a war against the Islam, basically those verses can be applied for what they actually say.
Of course, the perverse part is that the easiest was to defuse that would be to just start leaving them alone. You can't convince people to apply, say, 2:191, if 2:190 says they don't have to, and 2:192-193 say they should stop.
But yeah, good luck with selling that idea to idiot fundies who do want a new crusade to spread the word of their deranged Lord.
