I don't know much about politics, yet it think i know more that the Iraqi politicians, or maybe the vast majority of them.
Why would i say that?
Here's why...
Turkey says that the PKK is using the rugged mountains of northern Iraq (Iraqi Kurdistan) as a launch pad for attacks against its troops in the southeastern part of Turkey (populated by Kurds as well).
Now, right till this moment, the Turkish Parliament approved military intervention authorization, valid for one year. The Kurdish Regional Government of Northern Iraq said that it will respond to any military intervention. The US Secretary of Defense said that the US (and Iraq) would react to this case if an attack occured, or in a way that would eliminate the PKK rebels.
Now if you read the previous sentance again, you would find that the Iraqi Government based in Baghdad has not said anything in this regard, other than saying that they consider the PKK as "persona non grata", and its hopes that things would be solved diplomatically; not mentioning the Turkish bombardment of the borderline, or the presence of 200 thousand Turkish soldiers! That is an impressing number if we recall that the US Army present in Iraq has a total of only 160 thousand nationwide!
The Government is "logically" responsible for protecting every inch of the National soil. May it be in the north, south, east or west of the country. At least the theory says so. But the Iraqi Gov't practice concentrates on how the Gov't members (and also Parliament members) think about themselves, and how they steal the Iraqi people's wealth, perhaps with each politician hiding behind the banner of his ethnicity or sect, while not paying the slightest attention to the Iraqi people, whether the people were of that politician's ethnicity or sect, or not!
If the Iraqi Gov't didn't take a national stand against any possible invasion, then we must not expect that the USA would! But if it did, then perhaps it would be better if we were annexed by the US. It is better than being annexed by Iran, and that's what some of the "Iraqi" politicians wish!
Iraq is Iraq, and every inch of Iraq counts. Anyone who respects Iraq is worth respect, and anyone who doesn't is simply not worth being respected. This includes, but it's not limited to, the Arab neighbors, as well as Iran and Turkey.
As for the way i see it, i certainly hope that things will be fine through peaceful ways, because i respect both cultures and peoples; The Turks and the Kurds. But if Turkey makes the aggression, then i hope that it would be minimal and only against the PKK. And at that time i will fully be with the Iraqi Kurds, for they will defend all of Iraq, not only Iraqi Kurdistan, at a time when the Baghdad Government is very busy doing nothing!
