The question would be what is the time gap between the Psalm 83 War and Gog and Magog? There will be enough time for Israel to think that it can live in peace, to become prosperous (they say it will take a year to start getting gas from the new off-shore gas fields)... but I don't expect it will be much longer than a year. I don't believe Iran will wait too long!
You’re ignoring Israel’s strategy.
When its time to push the “Psalm 83” button, as it is known in Israel, Iran is one of the primary targets.
Israel is the only real military power in the near and middle east, and their primary targets are not their neighbors in the near east, they are iran and pakistan.
