Iraq was never about sadam..nor was it about wmds...it was about iran...the ballistic missles iran owns..and irans clearly stated willingness to drop those missles on euro cities.
The best shot at hitting a missle is on its way up...before we invaded iraq...europe had little missle defense against anything launched from iran. Now, iraq is full of fire control radar and missle launch sites that will drop anything shot outta iran before it reaches cruising alltitude of a jetliner..with a 95% hit rate. And....those launch sites will be dstroyed before the remnants of the missle it shot hits the ground.
Another key strategy to the iraq/afghan invasions were...to surround and cut off iran on both sides....iran no longer has free unfettered access to jordan/syria to the west...nor to the east to pakistan...which iran used to spread islam to malysia...phillipines...and china. Iran is surrounded on both borders by intel/black ops fobs...logistical bases, etc.
So..be thankful because had we not taken those measures ten years ago..iran would surely already be lobbing missles at brussles, paris, berlin,rome, etc.

1. As far as I know the US troops left Iraq more or less completely (there are some to secure your embassy in Bagdad). Therefore I doubt that Iraq is full auf fire control radar or missle lauch sites to fight Iranian WMDs. There are rather plenty Iranian troops (Shiites) in Iraq in the meantime to fight against ISIS (Sunnis). Obummer gave up Iraq to Iran a long time ago. A surrender without need and a betrayal to roundabout 5000 GIs, who lost their life for the US in this godforsaken country. In my eyes the biggest American bust since the Vietnam war.
2. A silly question: What could be the strategical interest of Iran to drop missles on European cities? Since the UK and France are nuclear powers, such warfare could be quite unhealty for them. Furthermore everything they have comes from Germany. Germany is still their most important partner for technology, spare parts and products they can not buy in China. Iranian missles over Europe therefore are quite implausible.
