In case you didn't notice, Carbombya is a (very) thinly veiled dig at the real-world nation of Libya, whose militants were the Terrorist Boogeymen du jour in the 1980s. It's about as creative as naming a fictional country "Attackistan" or "Terrorahn" would be these days.
The plot deals with a conflict in a Middle East country that tactfully goes unnamed, undoubtedly because the state of that region fluctuates so much that it could be a waterslide park by the time this comes out.
And then, one fateful day (Oct. 8), a runaway asteroid, believed by scientists to be nearly twice the diameter of the late Orson Welles, slammed into the Earth and killed the dinosaurs, who by sheer bad luck all happened to be standing right where it landed. The massive impact turned the dinosaurs, via a process called photosynthesis, into oil; this oil was then gradually covered with a layer of sand, which in turn was gradually covered by a layer of people who hate each other, and thus the Middle East was formed.
