The Survivalist #26 Countdown

"The ravages of nuclear war have reduced America, the once-proud land of plenty, to a battle-seared landscape of blasted rubble and toxic waste. A few tattered pockets of civilization struggle against the tyranny of the totalitarian army's crushing military occupation. Only one man dares to challenge the enemies of freedom-John Thomas Rourke: ex-CIA Covert Operations Officer, weapons specialist and warrior... the ultimate Survivalist.
Sub-oceanic cracks in the Earth's crust threaten the safety of the free world. But John Rourke's team has the solution. Massive nuclear explosions strategically placed will avert certain disaster and the deaths of millions. But Deitrich Drimmer and his Nazi stormtroopers control the only cache of atomic weapons large enough to complete the plan. It's up to the Survivalist and his team of commando fighters to destroy the Nazi stronghold and seize the powerful bombs before the future of democracy and life itself are annihilated forever!"
