Thanks. I bring this up because it's currently 'fashionable' to believe that islamists are followers of the Nazi doctrine.
I am inclined towards the opposite view. The Nazi's imbibed their hatred of the Jews from islam.
How about the 'cause' of WW1? The assination of the Archduke Ferdinand:
Contrary to common belief, Princip was not a member of the Black Hand, but was a member of the group Young Bosnia (Mlada Bosna), which he joined in 1911. The Young Bosnia Movement was a group made up of Serbs, Croats, and Bosnian Muslims, committed to achieving independence for Bosnia.

Was Princip a useful idiot for islam?
I think in the Pre-WWI (essentially Edwardian Era) nationalism trumped everything. Islam was basically afraid of the West. British gunboats or French Foreign Legionaries would certainly see that the natives kept their tribal animosities or religious prejudices under control. Princips probably acted as a Slav first and being a Muslim probably never even appeared on his personal radar screen. The reason I am saying this is because I just finished a biography of Ataturk. He was a Balkan Muslim,to him and to other young Balkan Muslim intellectuals Islam represented the 'Dark Ages (No Surprise There!) and the West represented modernity. It probably was the same with Princips. The Ataturk biography infers that Balkan Muslims who had contact with the West, most likely through contact with Austia-Hungary were the most affected. All they had to do was compare A-H with the Ottomans !(I have no direct evidence for this other then reading between the lines in that biography!)
Also remember when the Ottomans joined the Central Powers the Sultan declared a Jihad against the Allied Powers, however in this case it was a Jihad where no one came ! The Arab tribes that allied themselves with the British (Allied Powers) were motivated by Nationalism not religion !(For example T.E. Lawrence & H. R. Philby{ the father of the infamous Cold War traitor 'Kim' Philby} to name a few "special operators", also the French has some success with Arab tribes also but not to the extent the British did!)
In my opinion Militant Islam is a byproduct of Cold War rivalry, senseless decolonization, failed Arab nationalism & population pressures. It is made worse by the continued spineless response by the West. Now we see a equally limp response from Israel. All this does is embolden the radicals.
