1. how did the boundaries of israel change between 1947 and 1949? 2. why did they change? 3. what future conflicts could occur from this change?

1) One point which nicely describes how the boundaries of Israel changed between 1947 and 1949 is that these boundaries expanded which was in favor of Israel and fit as a glove to its plans and designations.

2) The thing which lead to this change was that territories ,which were controlled by Arabs after the end of the British rule, has reduced due to forming of State of Israel. 

3) Such a change can not just expire without a trace, since the land was grabbed from one hands to another, other or the same force would like to retrieve a lost part of the map, so the most likely conflcit which may occur after it is war regarding territories and expansion. 

They showed the country that integration could be successful.
