The main problem the US has is trust and credibility. After the Iraq war, well, no-one is going to trust the US when it says a country has WMD unless they show actual photos of the leader of said country next to a clearly marked nuclear missile, smiling and can then prove said photos were not photoshopped. That's how low the credibility of US intelligence is. And in the Islamic world US credibility in general is practically zero. Any positive benefits from this policy would be wiped out by the increased loss of credibility and trust. As the ancient Chinese saying goes, the first time a stubborn man refuses to take any advice, puts all his effort into something he believes in and loses horribly you should at least admire him for his effort and gumption. The second time he does it it's a pattern. The third time he does it, he's a stubborn incompetent idiot and fool and you should execute him. Basically, it's forgivable to find yourself in a hole, esp. if you got there in good faith, but if you don't learn from your mistakes and stop digging you're a fool and deserve to have the hole cave in on you.
On the bright side of things, when I get into arguments in threads I can now say "Well the US military has an official *policy* of releasing misleading information and propaganda to fool its allies" so how can I trust these statements/numbers? Which I think kindof hightlights the problem with this policy...
