The authors built an alternate history in which 1992 a limited nuclear exchange and widespread use of biological and chemical weapons has killed nine out of every ten people in the world. The two coalitions were a Chinese-Irish-Afrikaaner versus a Russo-British coalition that eventually allies with the United States. Europe waffles and is mostly destroyed in the crossfire. The Israelis stood neutral and their sworn Arab enemies attacked Israel, but with little result. Egyptians bombers managed to hit Tel Aviv, but after that brief attack, the Arab world was all but destroyed by Israeli military might. As neutrals, Israel managed to avoid all but the lingering effects of the WMD (weapons of mass destruction) exchange and stands as one of the last prospering enclaves of humanity. In fact, Israel is so prosperous that they have an overpopulation problem. Enter story plot element one, Israel now hires out its excess population as mercenary soldiers to the rest of the world.
Meanwhile, in the shattered remnants of the USA, Texas declares independence and a second US civil war develops, with a Second Lone Star Republic arising driven by oil interests and the SA, Sons of the Alamo, a white supremacy Gestapo-like group holding the power behind the throne. Israeli mercenaries have been hired out to both sides of the war and the book's protagonists are a mixed unit of Israeli tankists and reinforcements from the federal government. Their mission is to penetrate the heart of Texas and rescue the kidnapped president of the USA.
However, the World War has not only destroyed the world's population, but along with that population went the many technicians who maintained the technology that not only drove high-tech societies, but their military machines as well. Any weapon surviving is thrust onto the field including W.W.II museum pieces, M-4 Shermans, M-3 Grants, and even a Stuart tank
No - I don't like Mad Max (which is ten times better) and I don't like this either. But sometimes I wonder what happens in the brain of a person that can write/read such books...
