As mentioned in the declassified documents written by Osama bin Laden, the founder of the Al Qaida predicted that the formation of the Islamic State will fail. This is only one of the revelations that the killed militant leader made that was uncovered by the U.S. Navy Seals during the raid on his compound in 2011.

According to bin Laden, jihadists looking to establish a caliphate will most likely fail if they do not defeat the other nations opposing them first. As noted by VOA News, one of the main obstacles extremist groups are facing is the lack of unity among the different factions, which can greatly decrease their chances of establishing an Islamic State.

"We should realize by now that in order to establish an Islamic State, we should destroy the international infidels because they against an Islamic State no matter how little it is," he wrote in the documents.

U.S. officials who analyzed the documents said that bin Laden believed that the only way to form a caliphate is to defeat the enemies first. Deviating from this order or plan will surely result in failure.

Aside from his views on the operations of jihadist groups, bin Laden also wrote about other important and interesting issues. One of this is his open letter to the U.S. public about the need to take action in order to stop climate change, according to Reuters.

In the letter addressed to the American people, he said that members of the public must launch a revolutionary action to urge President Barack Obama to focus on stopping or reversing the effects of global warming. He then noted that failure to do so will result in catastrophic environmental effects that can threaten humanity.

The documents, which dates back to the 1990s, contains about 113 letters, wills journal entries and various other files, CNN reported. They were recovered in 2001 in his compound in Abbottabad, Pakistan after he was killed by members of Seal Team 6.

According to the news site, bin Laden stated in his will that he had about $29 million and he wanted this to be donated to jihadist groups after his death. However, it is not yet clear if portions of the money were actually given to terrorists groups since the whereabouts of bin Laden's wealth is currently unknown.
