There is a direct line between people who were ever daft enough to believe in some threat from the Soviet Union, and people who were ever daft enough to believe in weapons of mass destruction in Iraq.
Today, those people believe a man who claims to have organised Live Aid on behalf of Czechoslovak intelligence (making him a source no less credible than Ahmed Chalibi was, or than numerous Cold War types were and are), backed up by a once promising scholar who has followed the well-worn path to pseudo-academic crankery, a journey also familiar from the Cold War and from the supporters of the Iraq War.
And they are determined to believe in a Stasi file that simply does not exist. Just as the weapons of mass destruction in Iraq simply did not exist. And just as the Soviet military threat simply did not exist, whatever the squaddies, including the posh squaddies, may have thought at the time.
