Look, your soldiers are too naïve or too stupid. When they're naïve they're just another victims thinking they are preserving the freedom of they country and freeing another one. When they're stupid they endagnger their lives, they make their families suffer (well if their families are stupid, not) and enjoy murdering, they might know there's no fair cause on what they're doing or not, but they enjoy killing, they enjoy watching dead bodies pile up, they enjoy murdering children, they enjoy watching at houses and vehicles burned up by their weapons, they might even enjoy to see some of their armsmates lying on floor dead.
I have heard and read of some cases of Unitedstatian soldiers that refuse to obey orders from their superiors to murder innocent people, for example, and that have been executed for that and sent back to US as "KIA". Lets remember when a unitedstatian soldier decided to throw some granades at his own barracks for example.
These soldiers, knowing it or not, are not there to preserve USA's freedom and to free another country, they're there to preserve USA's oppression and make that country join that opression. They're preserving USA's plutocracy's freedom in expense of Unitedstatian people's freedom and enslaving another country in the same way. They're there to open Iraqi market to Unitedstatan market in order for the latter to engulf the first, they're there to ensure one of the greatest oil reserves of the world to Unitedstatian companies, they are there to destroy Iraqi culture and subitute it by the Unitedstatian consumerist culture.
And to alma_carmesi. Well read what I wrote before, and, also, USA's contribution to the downfall of Fascism is practically nule. WWII was a great business for USA in order to get great incomes and to open as much of European markets to USA taking advantage of Europe's ruin. WWII had as objective to destroy USSR and bring profits to the capitalist world. In the process 60 million people were killed, several countries Ruined (specially USSR) and the two first atom bombs ever droped were tested on Japan killing hundreads of thousands and prserving radiation until these dates. Wonderful way to fight for other countries' freedom... dropping atom bombs at their cities.
