Ok, I usually do not involve myself in random conjecture and amateur 'deduction,' but look at that statement. Is it not possible that his 'televised' address may not be an 'actual' televised speech by UBL but instead a 'message!'
Let me explain: 9-11 could be said to have been a 'televised address' by UBL since in essence he 'broadcast' his message and goals to the enitre world in one fell swoop by attacking the Twin Towers. The media was basically covering the whole event live, everyone was glued to their screens, and it permeated every corner of the world.
Thus essentially he 'broadcast' a 'televised address' to the world....just not in the orthodox manner most people expect when the phrase 'televised address' is employed in a statement!
Now UBL is supposed to deliver another 'address,' this time on the 4th of July. Although this is mere speculation on my part, is it not possible (if not probable) that this message (if it actually is to be and not some mindless rambling by Jehadis afraid their leader is dead) may be in the form of some act? Think of it...attacking the US on the 4th would have such powerful impact due to the dates importance!
Something like hurting your enemy....and then rubbing salt on the wounds!
