I am not afraid because I already know who is going to win the war between good and evil.
I understand your point that the evil in Islam is more fundamental than the nature of a government, but its important to understand that such an evil can not thrive in a Democracy. The two are fundamentally incompatible. Either the democracy will fade into a façade of democracy like in Saudi Arabia or Islam will mix and/or reform like in Turkey and Indonesia. Since declaring war on an idea (Islamism) rather than a practice is incompatible with a good in democracy, weve instead chosen a strategy of aggressively promoting democracies at Islams geographical and ideological core rather than attacking Islam directly.
So thats why I took issue with your concern that democracy is no match for Islam. Were going to force it to reform for its survival (and for ours).
