If the western world wanted to apply pressure to Zimbabwe and/or the surrounding countries, the way to do it would be to withdraw ALL aid and trade and make it clear that it wouldn't be resumed until matters were resolved.

They would also need to address the issue of how some banks do business out there. Barclays for example, donate something like UKŁ50M - US$100 M a year supporting the Mugabe regime. - Just do a Google search on Barclays Bank and Robert Mugabe to find out more........ What they get in return is a matter of speculation, but you can bet your life they're getting something very valuable in exchange

I'm sure the western Governments wouldn't try to enforce a blockade on people going into the country...... in fact, as Bramble says, it'd be impossible, but they could forbid their citizens from doing entering the country under some kind of penalty. - That would be a disgrace, but it's not impossible. It is unlikely, but not impossible........ after all, Big Brother is watching more and more every day.
