1. Turkey is doing pretty much everything it can to gain full member status in the European Union and a crackdown on its Kurdish citizens wouldn't really play well. I don't really see why you think this would become a civil war situation.
2. There's a devastating war going on now between Sunni and Shia.. and with even further breakdowns. What situation could possibly be worse than it already is? Everybody wants control. If Iraq is partitioned, each group will have more control over their own government and their own lives. It will not end sectarian conflict but it will ameliorate conditions quite a bit. The two groups will never get along --- and they haven't for centuries. Saddam Hussein held together the country by FORCE. The Shia will not cede power to Sunnis or vice versa.
A Shi'ite southern state would certainly align itself with Iran -- what of it? It is pretty much the global consensus that the Iran isn't really a threat. Israel might feel differently about that but it is not the job of other nations to bail out Israel.
The Iraqi government has had over four years to stabilize the country. Have they succeeded? Have they made any tangeable progress whatsoever? From everything I've read the answer is no on both counts. While certain US presidential candidates might think its a good idea to stay in Iraq for "a million years" it makes little sense to keep trying something which has failed over and over again. Iraq must be partitioned. Its the only way.
