How did Alliance Systems cause WWI? Secret alliances were formed prior to the outbreak of the war. After the Assassination of Franz Ferdinand the Archduke of Austria-Hungary the alliance systems went into effect leading to many nations protecting one another (i.e. Russia protecting Serbia from Austria-Hungary). Alliances prevented larger, stronger states from waging war on the smaller, weaker states.
The boundaries changed, that is, increased in Israel's favor. The Arab controlled territory was reduced. It was increased after the British rule ended when the State of Israel was formed. Future conflicts could be war regarding territories and expansion.
