There are extreme viewpoints in every nation, including those who have not seen war for decades. However, there is big difference between those. Yes, there are some people in Israel that deny palestinians their right to statehood, and so on and so forth... but they are minority in Israel and they don't fight their own private war like Hamas does. If they try to turn violent, they are arrested, persecuted and jailed. There are many examples of that. Palestinian extremes however have support, both from ordinary people and officials, and they carry arms to commit terrorist attacks. They are never brought to justice by palestinian authority, and they have more power than any extreme group in Israel. That is why I see hamas and militant islam generally as a threat, both to Israel and also to the western world. Israeli extremes are kept in order by israeli police and security forces, so they are not really big threat to anyone. EU makes a huge mistake, if it thinks Hamas can be negotiated with. It wouldn't be the first time europeans mess things up... they never learn.
