When one takes a look at this, one can clearly see that he was heavily into some disturbing radical Islamic stuff, centred around an uprising and fight for global Islamic dominance.

Among his content, he references a video/book called "Black Flags from Khorasan", which is supposedly a prophecy of Muhammad about a non-stop army that will rise from the land of Khorasan holding Black Flags of Islam in the end times. This army will conquer several occupied lands of Muslims till it reaches to Jerusalem. Then it will pledge its allegiance to Imam al Mahdi - I think this is supposed to be the Islamic Messiah.

Khorasan is apparently an ancient area that is part of the current Iran...

...the plot thickens and for all those claiming false flags, put your heads back in the sand - This is, as has been indicated, at least about a disturbed young who has been indoctrinated by Islamic radicals, with their usual anti-Western vitriol, but at worst, it is part of a spiraling terror campaign as young disillusioned Muslims are twisted into terrorists.

Who were his teachers and what are their links? People with links to Iran and Hezbollah are likely to be behind this indoctrination.

The younger brother, was probably an unfortunate pawn, dragged into this by his older brother.
