Thay may have been true before the invasion, but it's certainly not true now. Americans are very aware that Turky has been mouthing a lot of anti-American sentiment.
The government there might feel that by placating anti-American sentiment they can ensure a governing majority in perpetuity. They might even believe that by bashing the United States, and obstructing us at the outset of Operation Freedom, they will be able to deflect attention from legislative initiatives that are extremely unpopular among the most chauvinistic segments of Turkish society, e.g., their concessions vis-a-vis the status of Cyprus, and recent moves to grant the Kurds more autonomy within Turkish society.
However, if they think that the United States will rapidly forget the slights they have suffered at the hands of their putative allies, and supposed strategic partners, they are sorely mistaken.
Really? I watch and read the news every day, and read FR, and am not the least bit aware of and Turkish "anti-American sentiment".
And no Americans I know are aware of it either.
I'm not saying it doesn't exist...just that Turkey flies below the radar. Nobody here cares.
