Check out the home page of the Missile Defense Agency.
The logo -- or actually the mark, to be precise -- seems a tad familiar.
Compare and contrast:
The star and crescent "is most widely recognized as a symbol of Islam... [and a] number of Muslim-majority nations, such as Algeria, Tunisia, Comoros, Mauritania, Malaysia, Pakistan, Maldives, Azerbaijan, Uzbekistan, Turkmenistan and non-sovereign nations such as East Turkestan use it on their national flag."
If it were up to me, the logo would consist of a terrorist getting his head blown off, but then that's only one man's opinion.
Update: Dan Riehl has more.
