Sorry but the OP is correct... this situation *has* been manufactured by the USA's long-standing practice of pissing in other people's pools.
If the USA (and other Western nations) just kept their noses out of other country's politics then there wouldn't be this rapidly growing anti-western sentiment within the Middle East.
Hell... the USA and UK invade Iraq on the fraudulent proposition that Saddam had a stockpile of weapons of mass destruction -- and look how that turned out.
The USA has almost certainly killed more innocent men, women and children (conveniently categorised as "collateral damage") through their drone strikes than daesh has ever beheaded, shot or blown up.
The USA regularly executes its own citizens (hello Texas???) who the feel have violated their rules (rape/murder) -- yet complain so loudly when other cultures, religions or countries do the same.
Message to the US government: do not expect *anyone* to be pleased if you piss in their pool. Do not act surprised when those people decide to come piss in your pool.
I believe that what daesh and Al Quaeda have done is totally barbaric -- but then again, the same can be said for those Western nations who have engaged in acts of terrorism and murder against other nations.
Let he who is without sin ... as they say.
Why doesn't everyone just grow up and start acting like adults for a change????
