A lot of news coverage on potential Islamicist threats to US targets on July 4 (see this CNN article); something jogged my memory, and it occurred to me:
July 4 is also the date of the famous Battle of Hattin/Tiberias, at which Saladin defeated Guy, King of Jerusalem and his army of Crusaders and effectively ended the Frankish occupation of Palestine.
Since we know Al Queida knows their history, Id be definitely be in Condition Yellow that day.
