Yes, God has said what He will do but He has not said "when" or which "this" is this.
"This" was not the sacking of Jerusalem and the destruction of Solomon's Temple in 586 B.C.
"This" was not the sacking of Jerusalem and the destruction of the Second Temple in 70 A.D.
"This" was not the destruction of most of Western Europe's Jewish population in 1940's.
"This" might not be the destruction of the political State of Israel in 2012 A.D.
"This" might not occur until the Second State of Israel or the Third State of Israel (France is already up to the Fifth Republic) does battle in the 23rd Century.
Do not presume that you know what God's plans are for the 21st Century.
Gratuitous advice, since it works in ALL directions.
And what the heck does France and the number of iterations it's gone through have to do with the subject at hand? Israel occupies her own Biblical plane.
Nobody has said they know WHEN God will save Israel. We have been told in the Bible that He WILL save Israel, and that is the promise we hold faith in.
