First, there have been THREE Iraq wars since 1990.
Two of which was the US trying to protect countries around Iraq (and the oil involved), the third is the most recent one where they have been looking for WMDs all this time.
I think you're misunderstanding what a military is for.
A military presence is not for humanitarian reasons. They are supposed to be there to kill the enemy.
It's all the bleeding-heart/hand-holding left-wingers who believe the soldier should be giving hugs to all the civilians as they march through the town blowing things up.
The reason the US has had such a difficult time with recent wars (like Afghanistan, Iraq, Vietnam, Korea) is because of the hand-holding politicians who force the military to sit on their heels in favour of "negotiations" that don't happen or solve anything. All the negotiations should be made before the military is even called. Once armed forces are sent in, there should be no more discussions, other than a "surrender". Anyone who does not want to be shot, should put their hands on their heads and get on their knees, and then pray the soldiers are in a good mood that day.
I think it is summed up best in the movie The Siege, with Bruce Willis' character talking about bringing an Army into NYC. While we're talking about the military being deployed in foreign lands, we're also talking about the same thing...the military being moved in to combat an enemy, particularly one that is hiding.
General William Devereaux:
Twelve hours after the President gives the order we can be on the
ground. One light infantry division of 10,700 men, elements of the Rapid
Deployment Force, Special Forces, Delta, APCs, helicopters, tanks, and
of course the ubiquitous M16A1 assault rifle. A humble enough weapon
until you see it in the hands of a man outside your local bowling alley
or 7-11. It will be noisy. It will be scary, and it will not be mistaken
for a VFW parade.
Army General:
I wanna remind you, General Devereaux does not speak for official
Army policy. A police function has become accepted as our role in Haiti
and Somalia.
General William Devereaux:
Make no mistake. We will hunt down the enemy. We will find the enemy.
And we will kill the enemy. No card-carrying member of the ACLU is more
deadset against it than I am. Which is why I urge you - I *implore* you
- do not consider this as an option.
