Why iraq's people kill soldiers

U.S. and U.K. release iraq's people from suppression.
But iraq's people kill soldiers of U.S. and U.K.
Why?
 
Please teach...

The US didn't really invade Iraq for WMD or because Saddam was evil, or even for oil.  The first two reasons were only important because they gave a politically plausable excuse to invade.  Everyone knows that despite the vast oil wealth, the political and economic costs of a war to secure the resources would not be worthwhile, so long as OPEC operates at a reasonable market level, which they do.

The first two reasons...  of course Saddam is an evil bastard.  His human rights are almost as bad as Stalin or Hitler's.  Not very well liked.  Everyone knows he WANTED WMDs.  He didn't ever really have any.  If he did, Israel would have blown him up before he could bring them online.  (As they did in the '80s to a breeder reactor France gave him)  We did think we would find SOMETHING there we could point to, and were a bit surprised there was really nothing substantial.

We really invaded though to create a staging area in the middle east, and more importantly, to change Saudi Arabia's policy against Al-Qaeda recruitment and support.  Even after September 11th, Al-Qaeda continued to receive most of its money and personnell from Saudi Arabia, and the house of Saud couldn't really do anything about it, even though the US was pressuring them so much to stop.  So we took Iraq.  Now we have a bunch of tanks across from Saudi Arabia's border.  We're showing we're not afraid to bleed in a war (thanks to Bush's unilateralism and ignoring his populace, or whatever)  Our public opinion has always always been a problem, and been the only way to defeat us...  Well, I think that's a digression at thsi point.

A bunch of tanks across Saudi's Border.  Showed how much our military abilities have improved.  Our ability to launch quick wars (though that's more applicable to Afghanistan, where 'our' is in questionable).  Our ability to launch wars without access to Saudi ports, or significant support from neighboring countries (Though Iran has been helpful several times in the war on terror)

It wasn't even a unilateral war.  It just looked like it.  There wasn't the Middle-eastern support of the first war, but they think we're inept weaklings after Desert Storm and Afghanistan.    We had the support of most european states.  France, Germany, and Russia oppose our actions in Iraq because it will increase our power in the area.  So of course they oppose anything we're going to do there.  The other european nations fear France, Germany, and Russian dominance, so they actually ran away from the proposed alliance against us.  "In the end, the only countries siding with France, Germany, and Russia were Belgium, Sweden, Greece, and Belarus."  Don't forget about Poland, indeed.

So how is taking over Iraq going to convince the Saudis to crack down on support for Al-Qaeda?  Well, mostly it is the threat of flooding the world market with Iraqi oil, making the Saudi economy (hurting for the last decade) totally tank.  The threat of a possibly hostile American miltary across the border is not insignificant, but we're better behaved if we get our way.  Al-Qaeda HATES the US.  They know how to escape from our intelligence services.  They don't even fear our attacks because we've haven't shown any ability to endure casualties in a war since Korea.  The US invaded Iraq in their OWN interest to stop Al-Qaeda and demonstrate our military resolve and power to a middle-east that HATES us.  They're going to hate us no matter what we do.  With an american military presence in Iraq, they at least fear our ability to launch meaningful reprisals against them.  (Both Al-Qaeda and countries that support them)

And about Shock and Awe...  That was for our media more than Iraq.  The bombing and air-war in Iraq was much less significant than in Desert Storm.  In the intervening decade, they had not been able to significantly rebuild any targets we cared to bomb.
