We learn from history that we have to be watchful of political trends. The Taliban takeover was not a military victory alone. Other religious organizations like Jamiat-e Islah and Hezbutahrir prepared the ground for them with years of grassroots activism, ironically, under the watch of the American-supported government. The same goes for India, where grassroots religious organizations paved the way for Modi's walk to power. Your concerns about Christian Theocracy taking over the US is very well justified.
