Sure it depend on writer but the overall website owner still has the control of what he wants to post in his website. The fact, he allows such article to post show his sentiment. He can easily reject such article as it does not bent well on US superiority..
Seriously, many US self bragging article praising American military superiority are sometimes so absurd that any readers with normal IQ can sense the flaw in it... There is a limit of propaganda. End of the days, most readers are no idiot. If a lie is too big, it will have the side effect instead of the misleading you want to create.
