Judaism was seen as the main obstacle before other religions in the race of being largest religion. There were ethnic differences and also conflicts over lands. The big reason is that, out of four Abrahamic religions, only Judaism claimed firmly that Jesus and Jerusalem belonged to them. So they were the threat for growing Christianity at that time. And these differences and fear of other religion caused anti Jewish sentiments. Germans coined the term antisemitism for this hatred of Jews. Practically it means Jews are inferior race and belong to no land.
Now what happens when a community is discriminated for centuries… they unite… they find their own philosophies to disapprove the claims of opposition. So here we have a Jewish writer in the dawn of 19th century with the idea of Zionism which states that whole land of Palestine belongs to Jews as per the history. This idea was in existence before also but it never got such attention globally. It was discussed, criticized and supported at mass level.
Then after a couple of decades first world war happened and ended with intense humiliation of Germany. This defeat and disgrace was unbearable for Germans and their frustration was at its peak. They were not able to accept it and of course this guilt pushed them to find a scapegoat, a reason of national shame. So why search for causes when you already have a centuries old well established social myth ? Just give this myth some air and it will become truth for millions. There were already people like Adolf Hitler in Germany with exaggerated and misguided nationalism and desire to go high in Ranks and control people. In my opinion, such guys used antisemitism as the tool to unite a defeated nation and also for becoming personality cult.
In first half of 20th century, political scenarios were changing. Colonies were becoming countries. Monarchies were becoming democracies and communism was spreading like tweets of lady gaga. Russia, Italy and Germany had powerful dictators with similar intentions. They joined hands and made promises of helping each other in their causes. Imperial powers were weakening and communists were rising, tension was high. That is when Hitler designed Antisemitic legislation. Invasion of Poland initiated the darkest war of planet and Nazi party implemented their philosophies in the shade of the war. It ended with ethnic cleansing of Jews from Germany.
Now, there was a community of millions with no home. They had survived and seen mass-shooting, gas chambers, chemical experiments and concentration camps. That is when they adopted Zionism in real and moved to east in search for home, a place surrounded by Arabs. Pain and unity of a suppressed community gave birth to undying nationalism. They were ready to sacrifice anything for a country of their own and since then war is going on.
But there were also Jews who moved to Allied nations. Their grief was equally large and they decided to grow as a community. Be it science and technology, politics, cinema, business, literature or bureaucracy , they grew like anything. By the end of 20th century, they became major stakeholders in American economy and politics. They made propaganda movies and wrote accounts of the holocaust and it brought them lots of sympathy from outside. They were in position to affect decisions of world powers in their favor and that is what they did. American jews provided financial and political aid to Israel.
In the war with Palestine, that insecurity of Israel grew rapidly. They were becoming more offensive, answering every attack with doubled aggression. Palestine was a weak nation so it became a nursery for Armed groups. PLO and HAMAS grew in this atmosphere, kept recruiting people and also won elections. But still they were weak and needed some global approval to survive. This approval they get from rivals of USA who don’t like to be a part of any agenda run for/by American favor. America does this too. So USA, UK, EU, Canada and other friends declared HAMAS a terrorist group but Russia and China don’t agree with that. This complex involvement of global stakeholders worsened the situation.
Now it is 2014. After Second Intifada and downfall of Fatah, conditions are worst. Gaza is smelling smoke. HAMAS is making children suicide bombers and Israel is in kick-ass mode. HAMAS can’t step back because if they do so, they won’t get a single penny from their endorsers. They are finished ideologically and financially if they stop the war. Israel has also gone too far in it and if they call it then it means they are not fully convinced with the basic idea of their own war. That will mean they agree they don’t belong to this land. It becomes a threat to the ruling party there. Also Israel has dragged many outsiders in it for their support, so stepping back is diplomatic defeat in their eyes.
If both parties are unable to stop it then is it ever going to stop ? Global powers will never agree due to their own reasons. If HAMAS gets paralyzed then other groups will take over. Hatred is installed deep in the brains and Israel has developed weapons to treat it. Such issues never get corrected until there is a world war. Dooms day fights end these conflicts temporarily and end a whole generation also. Then again after 50 years, cycle repeats itself.
These problems never get solved because their roots are human desires which never end. Power, greed and hate gave birth to Israel and are still driving this show. Seems it will go on. Hallelujah!!
