Not even.
"Ages" can't clash. It's not like colors...
And the other impossibility: in order to clash physically the civilizations must both be contemporaneous (look it up).
One having died an imperfect death 1000 years ago, does not alter reality.
If current islam is any part of a civilization I fail to see any evidence of it. It has been said that the most numerous living things on the planet are termites, but I would never ever suggest that they are a "civilization"...
Sounds like you haven't read the article. She is clearly saying that the Islamist societies aren't playing with the same cards as the civilized ones.
They might say it, but that don't make it so.
Bacteria win, by many miles.
" One having died an imperfect death 1000 years ago, does not alter reality."
If your analogy is correct, then the Islam we are now at war with must qualify as the oldest and most dangerous zombie yet recorded.
I suspect that closer analysis will show Islam to be all too "alive". Perhaps you might consider euthanizing that analogy?
