Many have suspicions on the said events have come up with several seemingly plausible reasons for this outcome. First, there might have been WMD found but were from the US itself (whether obtained legally or not) for the US supported Iraq and was partially responsible for placing Saddam in power as they supported his drive to throw out the radical leaders of past. Rumors of the US invading Iraq on grounds of the possible gains they could get from the oil rich nation commercially was also plausible (Iraq is the second largest producer of oil on earth before they were invaded). Many more conspiracy theories are out in the thick of the events that may have caused the war in Iraq and the reasons for their utter failure in getting in and out quick.
It may be too soon to say what the outcome of their invasion would become of in the next few years. The only thing that is sure is that Western soldiers are fighting a war they seem not to be winning. They gain ground today, only to loose it tomorrow to militants and whoever they find as enemies. Their changing tactics show the desperation in the military trying to shift policy, trying to get out of the battle; recruiting former Saddam military and police officials and personnel; allying themselves with previously tagged insurgent groups and militia; and many more. They have to get out and start considering the impact of their actions on the lives of the grunts who have to walk the thin line between life and death each and everyday. People still die everyday, some known and documented most are not. When will they learn to accept defeat and just admit plain and simple that they made a mistake when they invaded the country. They cannot make the world a safer place for all of us for they themselves have internal problems of their own back home. The statistics may be showing that their drives to reduce violence is having an effect yet lives are still being lost and families have to live with the fact their children died for a lost cause.
