I once looked into the question: "Is there any proof from the Torah that the State of Israel will last until the messianic time."
I wasn't shown any clear proof that the country will somehow last that long and then morph into a G-d fearing one.

Although, if we go back to Esther's time there was a world wide repentence. Seems a tad far-fetched in the year 2006.

I wasn't shown any clear proof that the country will somehow last that long and then morph into a G-d fearing one.

You will find no such proof. However, one thing is certain and is amply documented in scripture is that regardless of what may occur, God will preserve a remnant of Israel for Himself. (See the book of Obadiah as an example of this, or the book of Ruth.)
