Of the need for unilateralism and how Britain can't go it alone.
Of how this wasn't an objection to any and all military intervention.
Of how the problems although bit fully crystallised could be foreseen in advance.
Of the need to listen to the reports from experts.
The idea that an enemy can simultaneously be seen as well and on the verge of collapse, but still seem as a clear and present danger.
The list goes on.
Of the need to apply the same rules to different cases.
Of the effect of narrow US elections on UK policy.
Of losing and alienating our traditional allies.
Unfortunately Westminster now has free politicians of such calibre and conscience.
RIP Robin Cook
