The devastation unleashed throughout central Europe by the Thirty Years War (1618-1648) was ended by an agreement, called the Peace of Westphalia.  This treaty included a declaration of non-interference in the domestic affairs of sovereign states.  In 1999 and for the next five years, British PM Tony Blair ran an aggressive campaign to move into a "post-Westphalian world", based on a doctrine of the "Responsibility to Protect", to justify regime change against sovereign nations which don't accept "our values."  Iraq, Libya, Ukraine and Syria have already been subjected to mass murder, and Russia and China are targeted.  Why? -- Because they don't share Mr Blair's "values", especially when those values include support for assassination of leaders (Libya), support of neo-Nazi militias committed to ethnic cleansing (Ukraine), and the arming and training of Jihadists, followed by famine-inducing sanctions, as in Syria.
