Rainbunny It's got f* all to do with "war fatigue". Do you suppose when there's a strategic, long-term economic incentive of our gov't to overthrow any other gov't, ME or wherever else, we'd ever shy away and say 'we're fed up with funding and fighting wars, we can't be bothered'?
"Doing nothing", let's take a look what our 'doing something' or interventions has got us. A hell on earth in Libya, vast sways of Afghanistan and Iraq. Now you propose we create more of the same - in Syria?
Without the crime we committed, that of aggressive war against Iraq, which has left more than a million innocent people dead, there'd be no ISIS and no Al Qaeda in Iraq. Without Saudi and Western funding and arming of extremist Sunni groups across the Middle East, we use as proxies to strike at Iran and its allies, there would be no ISIS either.
It's our leaders we ought to be holding to account for this sickness. Those doctrine-addled, testosterone-blinded morons in Paris who volunteered to kill themselves along with as many innocent people as possible, are just the rash it's all come out in.
