Except the UN would never do it. Heck half of UN organizations don't even operate in compliance with half of UN resolutions and sanctions.
The US leadership changed to a administration that wanted out of foreign affairs, so they pulled back in Iraq and AQ in Iraq became the root of ISIL. And now we see history repeats as the Taliban move back into the vacuum left by poor leadership.
Of course the UN would never do it, its become a pointless waste of money. I was saying that's what the UN should be for.
As for America, well IIRC, the withdraw was already planned and agreed by the Bush administration before Obama took office.
I see Obama getting way more than his fair share of the blame. But in this instance, he was merely following the roadmap set out and agreed upon by his predecessor. This move was also overwhelmingly popular amongst the American people.
Shouldn't really pin this one on Obama when all he was doing was uphold agreements already in place and execute the wishes of the majority of the American people.
Every time you loose a war, you always have people coming out of the woodworks afterwards (who never actually fought themselves) lamenting how the war would have been won had they been doing the leading (never the fighting amusingly enough).
All this blame-the-weak-willing-Obama is just a manifestation of that. With the implication the US could somehow have held everything together had another president "with balls" had been behind the desk, when in fact, any president would likely have done exactly the same thing, grand direction wise, because that was what the American people overwhelmingly wanted.
You are correct that history is being repeated, but what the American people and the world should blame the Obama administration for is its meddling in countries like Libya, Syria and Ukraine.
Even after the US pulled out of Iraq in earnest, Al-Q was a spent force and a threat even the Iraqi army could have handled.
It was the western back challenge financing, training and arming of "moderate" rebels in Libya and then Syria which created a new recruiting, training, proving ground and safe heaven for Global Jihadists Terrorists.
Many of the people the US would and probably should have been liquidating with drone strikes and special forces raids in Iraq and Afghanistan instead were given CIA money, weapons and training when they crossed into Libya and Syria. In effect, the CIA created a terrorist wonderland in Libya and much of Syria.
After the fall of Libya, many of these now well-trained, well-funded, well-connected and battle hardened hardcore Jihadists went back to Iraq and promptly wiped the floor with the Iraqi army and seized vast quantities of money, weapons and territory, which gave them the foundation on which to build ISIS.
