In the 1980s the Commonwealth nearly came apart at the seams because of Thatcher's intrasingent opposition to sanctions, a position shared by the Reagan administration. In particular, the ones pushing the hardest were the UK's staunchest allies most of the time: Australia, Canada, and India. In their respective memoirs, Thatcher, Hawke, Mulroney and Gandhi all make clear that things got extremely heated, often uncivil, and at some points there were calls for Britain's censure or even expulsion. So let's say that no one backs down, things escalate and one of those motions pass. What happens next? How long does it take to recover? Effects on the South African situation?
