How is the assassination of Archduke Franz Ferdinand connected to the current unrest in Iraq? According to this infographic from James Carson, founder and editor of the new website MadeFromHistory.com, the June 28, 1914 shooting of the Austro Hungarian prince and his wife Sofia in Sarajevo set in motion a sequence of events that not only produced the First World War, but all of the bloodiest milestones of the next 100 years. In fact, everything from the rise of Hitler and the Cold War to the Arab Israeli Conflict and 9/11 can all be traced back to the killing of the royal couple. See below. 
If I’m not mistaken, the longest, thickest arrow in your map leads from the creation of the State of Israel to the Iraq War. Is that not horribly re-regurgitating anti-Semitic talking points? That the genesis of the attack on the World Trade Center and Saddam’s desire for WMD can be traced back to the turmoil created by the presence of the Jewish state.
The history I learnt was that WWI led to the collapse of the Ottoman Empire and the Mandate for Palestine to create a Jewish National home, Israel. Funnily enough, Saddam’s stated reason for starting the first Gulf War was that he did not accept the Mandate for Mesopotamia cleaving out Kuwait.
Arguably, US involvement in the middle east came from their interest in securing global oil supplies, and the mess that was Afghanistan could be traced back to Soviet (another legacy of WWI) ambitions.
All this missed starting defeat of the Ottomans after WWI?! You won’t earn kudos from me for “seeing through” the straightforward narrative and linking Jewish self-determination to the ills of the 20th century.
I agree , the treaty of Versailles caused the 2 world war more than anything else ,the yoke and shame that was put on Germany was only going to eventually cause another conflict, just as it did.
