That's probably the point.
I agree completely. If they use this tactic a few times and get us to change our tactics they might hope to influence other Iraqi soldiers that surrendering is just as risky as fighting.
I'm sure they will increase the caution they approach the surrendering Iraqis with but I would not classify the strategy as one of recklessly endangering our troops for the sake of being PC as others on this thread have indicated. By taking this extra risk we will greatly enhance how other surrendering Iraqis (the ones that aren't faking their surrender will be the ones that survive the war) and their families and civiians will view the US after the war. If we can get a strong alliance with Iraq that is broadly supported by the population our chances of turning other ME countries inceases.
It is important to frame this war in the broader picture of the worldwide war on terror. Shock and Awe is not just a great strategy in this war, but the show that they are putting on for the world with all the embedded media is giving all the rest of the countries on the short list a look at coming attractions. Hopefully this will save lives and combat down the road and will make a few of these countries rethink a few policies.
I see the policy of erring on the side of protecting cvilians and being open to surrender having wider ramifications as to how well we will create a new prescence for ourselves in the ME and how other countires citizens and leaders view the US.
