I disagree, LH. It's easy to say "provocations occurred on both sides, but Israel initiated the full-scale war." All that means is that you decided one of Israel's moves was the start of the war. In fact, by not recognizing Israel, the Arab governments have mostly kept themselves in a perpetual state of war with Israel.

In 1956, Nasser stated outright that he wanted to destroy Israel, took command of the armies of Egypt, Syria and Jordan, then blockaded Eilat and Israel's access to the Suez Canal. These last were breaches of treaty and acts of war.

The whole question of Lebanon is irrelevant, because Israel did not annex any territory or claim it for Israel, which is what we were discussing. You wouldn't say that the US expanded its territory by occupying Japan in 1945. So we could argue the merits of that action, but it's not relevant to the size or territory of Israel.

In 1967, Israel did strike first, but after Egypt, Syria and Jordan mobilized their armies and made clear their intentions to attack. Even so, Israel struck only against Egypt; Jordan and Syria then attacked Israel. So the only claim you could make for Israel taking territory through aggression is the Gaza strip, and even that is a stretch.
