What is needed is a sensible balance of power, with Iran and North Korea held in check, and countries with regimes interested in creating trouble and “Global Caliphates” and reincarnated “Ottoman Empires”, brought appropriately to heel.

Russia and China are large and powerful, so with them we need rapprochement, trade and a focus on the young who represent their future. The present policy of trying to destabilise them with colour revolutions, umbrella revolutions and stirring up Uighurs, Tibetans and troublesome Muslims in Southern Russia is counter productive in that it creates more opportunities for jihadism and the potential for more refugees and economic migrants that we can frankly all do without.
