If we assume that an idiot such as Col. Bud Day who is quoted in this post's title represents all of the citizens of the United States then those outside the US would be justified in assuming that all US citizens are idiots. But Bud Day does not represent us and we are not all idiots such as he (though all humans seem to have some brand of idiocy in varying degrees).
Some Moslems do apparently believe that forceful conversion or death is the only options for dealing with non-believers but it's rather obvious that not all do believe so. (Christians are not so innocent in this regard either, by the way.)
And even if all Moslems did believe this way, what idiot thinks that before we invaded Iraq they had any chance of accomplishing such a feat. Before we invaded Iraq we could have just laughed in anyone in Iraq that claimed such a preposterous goal. We could have taken steps to protect us from the few crazies. We could have used old fashioned detective work to find those who actually did threaten us or did act out on those threats. And right after 9/11 we would have had the worlds support in going after those who actually planned and engineered 9/11.
After invading Iraq without cause and without benefit, we are weaker than we were (though 'the people who matter' are much, much richer). And if the Bush gang continues down this road and invades or bombs Iran we will be weaker still. We are collecting the hate of the world. We, as a country are very, very stupid. And too few of the non-stupid are in power at present.

ADDED: Just think, we placed Americans in Iraq as handy targets for any who would like to take a shot at them and then proceeded to treat the country in such a manner to increase the number of people who, and not necessarily for any reasons having to do with religion, want to kill and humiliate as many of us as they can. It's called hate and the monkey in the White House, George W. Bush (a self proclaimed Christian who evidently believes he is doing Gods work), is very, very good at engendering hate, cruelty and all that is base about humanity. What a legacy.
ADDED II: Speaking of God. Since the Moslem, Christian and Jewish God are the same God wouldn't 'believers' begin to wonder if they have understood the message correctly? Either this god is very much like George W Bush(cruel, vindictive, petty, and shallow) and deliberately setting his 'children' at each others throats for some cruel purpose of his own (which I'll admit I am unable to fathom) OR based on the more uplifting teaching of these same religions many are perverting the true teachings OR there is no god and those in power manipulate the message to whatever works to keep and increase their power.
