well i think that we have shown that we're prepared to support gorbachev in so far as er peace reform in the soviet union, but i think we've got to look towards our own security in the west and we've done very well with nato, with the defensive block nato over the last 40 years or so, and until we can have cast iron guarantees that gorbachev is going to be secure and that he's actually going to carry out his promises we've got to keep our guard up.
