The story is still developing as I write this so the long range implications are hard to predict. Israel was originally 7,000 sq miles until after the 1967 Arab-Israeli War at which time the territory expanded to its current 20,000 sq miles. At heart, this is what has driven much of the conflict. The territory acquired by Israel in 1967 is considered to be part of Jordan by most of the Arab world. As Israel was at war with Egypt, today's attack has profound symbolic roots for both sides.
