I mean, he's already in Zimbabwe.

He's bitching about Britain???

Spycatcher made it pretty clear that it was British political desision that reined in the intel opperations that would have given the Rhodesian Selous Scouts the information to take out his insurgent/terrorist "army" (go look up the definitions of both of them and make your own desisions on what kind of group he was leading).

He should be thanking whatever God(s) he belives in (if any, IIRC he was of the Marxist bent) that Britain did that. But hey, it's been 25-30 years since then and he may have forgotten that that is the only reason he lived.
