So? What business is it of Britain if another country wants to self destruct? Meddle with other people's affairs, expect consequences.
And Europe was "peaceful"? Really? "WORLD" war 1, 2, invasion and colonization of numerous countries across the globe with little or no provocation solely for Empire? Nuclear weapons, mass bombings with no regard for civilian casualties, Nagasaki, Hiroshima... I could go on.
The stupidity of some people in the war room is fkn astounding. People are people period, we kill, make war, and look out for our self interests regardless of culture or nation.
