In 1947-1948, when a large Jewish population has been transported by the British, due to a promise Mr. Balfour has made to the Jews in Britain. He promised them the holly land. Why? Because Hitler has just finished his massacres in world war 2, and who ever was able to flee, needed a home, and at the time Britain was not able to accommodate large population integration. Leading to the promise. Now the issue here is, the killing. The Palestinian government at the time did not refuse any immigration into it's lands, on the other hand, it always had it's arms open because it is a land gloabing 3 major religions the time (Christianity, Judaism And Islam).
Why did the British kill for the Jews? Why did the Palestinians defend their homes with gun fire? Why did one need to oppress the other?
Israel is a land in name, to be portrayed as a holy religious land. But if you hear what the orthodox Jews living their have to say, you would be surprised as to the recognition they receive for their religion is minimal. Israel is a national military base, yearly funded by the United States at a base rate of 147 billion dollars. That go into education, support, infrastructure, and military advancements and weapons. Judging by the price of weapons nowadays, the majority of the fund is spent their way. They're education system is 85% military oriented (which I find fabulous, every country should build citizen soldiers), where they have youth at 14 practicing war jet flights, parachute descents, etc.
They want an army, and army that will fight against who ever dislikes it, demolishing who ever stands in their way. Interestingly enough, the idealist behind "Israel as a country" and you can find the book, he said Israel will crumble after it's first lost war. In 2006 July, the 33 day war on Lebanon, terminated by a seas fire settled by united nations, having the Israel army not complete one of their goals, leaving the military minister to take his leave. The cost of the war to Israel was tremendous, having negative effects on it's population settlement. In the rule book of wars, that is a lost war.
There was never the need to fight, nobody forced you out, you forced yourself in. Because you feel safer if you hold control. -Natural human behavior
