America's prestige was destroyed by none other than George W. Bush, Dick Cheney, Donald Rumsfeld, Paul Bremmer, Rupert Murdoch, Colin Powell, Condoleeza Rice and several others, for a number of reasons, but most of all the 2003 invasion of Iraq, from which you can draw a straight line to ISIS.
How you "connect the dots" and manage to wander your way from Manning and land on Trump is beyond me. How you digress from WikiLeaks to Trump is curious.
Political influence may have elected Trump, but cones of silence, echo chambers and hacker mudslinging isn't really what got Trump elected.
Republican incompetence permitted his candidacy in the first place. Republican spite invoking a broad mistrust among suburbanites and rural America put him in office. If the people who voted Trump, are so easily deceived by falsified evidence and dubious non-journalism, then they were stupid enough to be deceived by anything, but wanted to be spiteful and hate something, and would have found something dubious to latch onto and excuse their shitty vote anyway.
