Israel is a major country and there is no reason for them to not have a seat on the U.N. Security Council. They have a very sophisticated military and know a great deal about security. They are basically a friendly country and are not threat to anyone. They are peaceful and deserve a place on the council.
No, Israel should not have a seat in the UN Security Council as Israel has been the source of much turmoil since its inception. Israel has repeatedly attacked Palestinian settlers in the Gaza Strip and in turn has been attacked by those settlers. Since Israel cannot safely defend itself, it has no place discussing security with the rest of the world.
