Now that it appears dictators of Muslim nations are going to be overthrown, will the Brotherhood bring peace?

For decades countries as Egypt,Tunisia,etc.lived pendulous lives, bridled with poverty. Living insupportable lives as their leaders enjoyed intemperance totally disaffected from those beneath them. And now,those who were suppressed insurrected themselves and are free to make of their lives as they determine. The Muslim Brotherhood is extending its compassionate arms out to them, offering them sanctity. Do you think that now, with the probable unification of all Muslims living out their rich heritage under the directive of the Brotherhood, Western so pro-claimed "Muslim" problems will dissipate? Will now,due to the contentment of Muslims to follow their dreams of living lives of holiness under Sharia Law,guided by the gentle nudging of the Brotherhood, both the West and the Muslim world live in harmony? Is peace, being finally given a chance??
