Just so you know, there are a few things wrong with you... and your argument.Freedom of speech...
The world is in a really bad economical siruation, and USA is still spending incredible amounts of money, if they wanted to, they could pull out of this war, stop the spending, and stop spending so much money on being the police of the world, as they try to be. They have no rights to judge other countries, when they have so many internal problems, an example is the mosque they are willing to build on ground Zero.
You say freedom of speech, which by my recollection was an American idea that allowed for the people of its country to not be oppressed vocally, religiously, or in the way they wanted to express themselves. As they had been in the countries that they had come from, and how the Brits were still trying to do to the colonies.
The US could have pulled out of Afghanistan earlier, that is true. But at what cost? The fact that they went in and destroyed the internal political structure made it impossible for them to just up and leave without first handing over the keys to the country to the Taliban. What the US should have done was spend its vast amounts of money to fund programs such as "Pennies for Peace" or just straight out fund the CAI (Central Asia Institute) with all of the money that they ended up putting into the army. That would have been the smarter thing to do. But Republicans are idiots that profit from the loss of others these days.
America has every right to judge other countries, they can pass judgment on whomever they want when ever they want. That is what makes them as powerful of an ally, or opponent as they are. If you take away that ability, you might as well change their name to Iceland while you're at it, because that's is how influential they would become. (no offense to Iceland)
Finally, as Rag said only more blunt, you are dumb! The only people that actually believe someone is trying to build a mosque as "ground zero" are morons, who have more time to stick their thumbs up their asses then they do to actually ask someone who knows. Though even if they did want to build a mosque at "ground zero" it would only be replacing the one that was destroyed in the first tower anyways. The Taliban, and Al-Qaeda burn more Korans, and break more Islamic laws than any other religion combined, and those other religions don't even follows the Islamic laws. That attack was not about religious beliefs, it was about fear.
Do everyone a favor and read a book... Try this one, if you can't understand it there is a children's reader version too... Three Cups of Tea
Back on topic: That Wikileaks guy had better watch his ass... but he'll probably die in an airplane "accident" soon enough anyway.
