Arens predicts peace. There is no way that Israel can eliminate the threat which has already been provoked and which continues to be provoked. Living under a "threat" is a byproduct of p0rovoking one's neighbors. So great has been Israel's provocation that it will take many years for the threat to ease even after the provocation stops. As for taking military steps to stop the threat, this only increases the threat. Arens should be old enough to realize this even though he is obviously not very wise. The only reason that Israel has done as well as it has is because the enemies of Israel have no significant weapons yet. This will certainly change with time. By adhering to strategies favored by such as Arens, Israel has only lost all international support while increasing the threat level.
