re withdrawal by Nato from some of the areas that they promised they wouldn't put bases in -
yes danger would be leaving those territories unprotected ,but surely some clever diplomat could come up with wording that withdrawal would be reversed if Russia appeared to be making moves ?
It's easy to adopt a stance where Putin is not to be engaged with but this is what has led us to where we are now .And things aren't black and white ,Putin is not the same thing as Russians .
Mediation works on the principle of hearing both sides and working towards a solution where both sides feel they have gained something .If we adoptia position where Russia must be overcome and crushed we are not only as bad as them but perpetuating the current situation .
