Terrorism and what to do about it

By now, unless you are living under a rock somewhere you have heard about the terrorist attack in Manchester in the U.K.  It was an Ariana Grande concert, so the victims; 22 killed and more than 60 wounded were mostly young girls.  The British authorities are treating this as a terror attack as it almost surely is.  The usual messages of sympathy and solidarity poured in from national leaders around the world.  The difference between the response of the British people and what would probably be the case if a similar attack occurred on American soil is stark.  The Brits are not obsessing about the possibility it was a Muslim terrorist.  They can't afford to since the area around Manchester is packed with Muslims.   As an NPR commenter put it, the US can still debate excluding Muslims because they are still a tiny minority in this country.  This is not the case in most European countries.   Trying to stigmatize Islam is not a viable policy alternative for them.  In this case and many others, we need to understand the reasons behind the decisions to commit these heinous acts.  To be honest, the policies of western democracies toward Muslim majority countries since WW1 and even before are mostly to blame and they haven't changed.  Until these underlying causes are addressed, more innocents will pay the price in venues like Manchester.
