The world's dislike of Israel is explained by the fact the world is uncomfortable seeing Jews in positions of authority. Its a radical change for a people that spent most of the past 2,000 years as a powerless minority. The sight of Jewish prime ministers, policemen, soldiers, civil servants, clergy, businessmen, farmers, artists, doctors and teachers wielding normal roles as the leading segment of a society takes getting used to. Even for Jews, it comes across as something completely different to find out that for Jews in Israel, behaving as a majority is a completely normal affair. Its the rest of the world that's still not adjusted to the reality of Jewish power and Israel's unique treatment can be explained by the world trying to treat a sovereign Jewish State the way it has always treated Jews: as inferiors who ought to do what they're told. And trying to change such an ingrained age-old mindset to treating the Jews as equals takes a great deal of time and effort. So Israelis know they have the power to decide their own fate and this alone bestows on them a certain sense of reassurance even if the rest of the world is prejudiced on the score of Jewish power. For the first time in 2,000 years, what happens in the Jewish future will be determined by what Jews in one small country do and not by the actions of others around them. Therein lies the revolutionary significance of Israel's existence in a world that still doesn't quite understand her on her own terms.
(The Palestinian terrorist regime is the crisis and Israel's fist is the answer.)
The very idea of what Israelis have accomplished on that strip of land beside the Mediterranean in the past 60 years, is received as a body blow to many people. Their answer to this irrefutable evidence of what can be done with Rule of Law, cooperation, industriousness, etc is to wish it gone.
When the Palestinians were left the physical structure of the Gaza strip last year after the departure of the Israelis, instead of continuing with the industries established there, greenhouses for example, they destroyed them. That is irrational, yet indicative of the mentality of the people who have only one goal in life. Eradication of Jews.
How they think their lives would improve if there was no Israel, is unanswerable.
