We are at a stage where tank missiles are recognising a profile & not only heat. The next progression is being fought off by the US especially, because of advances in chaff which are thought to make their Airforce safe to establish air superiority & so win every conflict. Unreasonable.
The more military aircraft shot down the less damage (by an estimated quarter less) will result from nuclear catastrophe. There is a mission to kill those who are opposing this debate as well as the downing of aircraft by progressive technology. Money is available if you need it but we disrespect you if you do.
