West is best at overthrowing governments it calls regimes

Why should a government NOT be ruthless in putting down a rebellion?  Any UK government would be.  Even the good people of Scotland in 2014 had the fear of God put up them, if they dared to be so stroppy as to vote for independence from big brother England.  Our problem, in our so well meaning, we know what is best for you fortress, is supporting the rebels to overthrow their governments in Afghanistan, Iraq and now Syria.  And look where it gets us.
