I'm not overly intelligent, but I have to ask how the filter in a gas mask filters-out the methanol in the stuff? Methanol is wood alcohol; it's deadly when ingested. I have read that the crews who serviced and maintained the Soviet jet fighters that were stationed in the far north regions of the country would drink the alcohol that was used to do something (I know not what) in the jet engines. You have to be pretty sad to do that, which would leave your Air Force less than ready to respond from an attack or an incursion from China.. . . filter anti-freeze through gas masks to drink!
Praise God Ronald Raegan was able to destroy the Soviets without firing a shot. He said we'd build the "Star Wars" defense system-- the Strategic Defense Initiative. The Russkis knew we had both the technology and the money to do it. They also knew that they had neither. It took until August 16, 1991 for the Soviets to fall, but they did. Rush Limbaugh said the Soviet Union fell under the weight of its own immorality. The natural yearning of the human spirit is to be free. Communism defies Individual Freedom; that's immoral. An unstoppable force met an immovable object. The object moved, and 300 million people were liberated. You gotta love that...
