That's a very optimistic outlook on that...
I remember going into Iraq and ....
But North Korea has pretty much stayed the same.
- Destablizing the country.
- Throwing out and disenfranchising the Baath Army.
- In turn creating Al-Qaeda in Iraq and a separate Sunni insurgency.
- Removing the only effective counter to Iran.
- Watching Iran grow in strength.
- Further bolstering insurgent groups (ex: Hezbollah)
- Being a major player in the Syrian and Iraqi governments
- Soon after destabilizing the ME region.
- Which led to the civil war in Syria.
- Which led to the creation of ISIS.
- Which led to the neutering of Saudi Arabia.
- And which led to the deft maneuvering of Turkey which in fact assisted ISIS earlier in the Syrian civil war to further damage rival Syria.
Sure, Iraq was a fuck-up. But comparing the Axis of Evil to the WWII-Axis (which you were implying) is out of proportion. Even if media blow everything up, we're still faaar from the wars in the first half of the 20th century.
Also, I'd argue that the Syrian civil war didn't grow out of the Iraq War. The Arab Spring started in Tunisia, after all, and the sparked conflicts everywhere from Algeria to Yemen, unrelated to the Iraq War. Also, Saudi-Arabia has a lot of dirt in its backyard as well - Saudi ideology took a pretty big part in creating modern day radical islam, and early in the war, the gulf states poured money into nigh every rebel group regardless of it's outlook, most likely also the IS, and they have their own bombing campaign in Yemen.
