The current situation in Iraq is worrying. With the rise of extremist Islamist group ISIS- or ISIL (Islamic State of Iraq and Syria/the Levant) in the southern part of Iraq there are major concerns for human rights as the following UN article reflects: United Nations News Centre - Iraq: UN envoy demands Islamist forces end ?horrific terrorist acts? . However this doesn't appear to be a simple thing of sending US troops back into the streets of Iraq (for the moment at least). This thread will be for discussion on Iraq, the effects on its neighbours and effects on its western allies (should we call them that). Seeings as a major city in Iraq has been taken by these people, it's clearly important enough to bear in mind.
Agent Nationaux correctly alluded to how this situation is similar to post- Soviet invasion Afghanistan. This is a fair comparison seeings how it was created by a foreign invasion which only created a power vacuum. Furthermore the US and its western allies have by no means gone out of their way to give resounding support for the people who we should be helping (Ahmad Shah Massoud comes to mind in Afghanistan and the Baghdad government which has received only limited help with no obvious military results). Thus Iraq should be the lesson the US should've learned in the 1990s that if you intervene in a country, you should try to stay until the job is properly done. Furthermore this comparison reflects the predictable nature of this sequence of events and thus should have been avoided.
Lastly I want to reflect the complex situation. With so many group vying for control and/or autonomy the situation is complex and not easy to solve. The following article reflects this: BBC News - Struggle for Iraq: In maps
I hope it goes without saying that we should avoid discussing the intricacies of Islam and whether it's good or bad.
