The Fall and Rise of Yisrael

During Yehu's reign Aram, headed by Hazael occupy the Eastern bank of the Jordan. In Yehoahaz's time the situation becomes direr as Aram imposes a full demilitarization of Israel. The turnaround begins in the days of Yoash who receives a deathbed prophecy from Elisha of a victory over Aram and peaks in the time of Yerovam ben Yoash who receives a prophecy from Yona ben Amitai and restores the Northern border to a magnitude previously witnessed only during the days of David and Shlomo. While historians describe the decline of Aram due to the rise of Assyria, the book of Kings describes a divine process which is surprisingly almost entirely devoid of any repentance. 

Does the outcome of the prophetic action that Elisha preforms with Yoash on his deathbed actually have an impact on the outcome in reality?

Is the resurrection from death of the man who came in contact with Elisha's buried bones just another miracle of Elisha or does it symbolize a national resurrection?
