The yells and howls, growls and curses, that followed the explosions in Boston were beyond description. If asked, I would be at a complete loss to tell what happened exactly. After 911 the USA did manage to keep on existing in people's mind as an “untouchable” nation, god knows how. Now, twelve years later, can they do the same? Or, will they buckle under the weight of their keeping up a facade of invulnerability?
Did I use the word "facade" in the right way? And what about the text as a whole?
Thank you in advance!
