What has been happening to the nation of Israel in the dry bones analogy?

Les explains that Ezekiel 37's valley of dry bones was a picture of the nation of Israel, which had been out of the land of promise, away from temple worship, and blinded. The bones were very dry and white as snow, showing how long the nation had been in that condition. But God is going to bring them back to life. Les teaches that this is pictured in Israel coming back to their homeland, as seen for the last 48 years since their 48th Independence Day. The nation has been shaking and rattling and coming back to life, returning to Israel from every nation under heaven. The muscle has come back on the bones and the skin is coming back, but there is still no life spiritually; they are still spiritually dead. This is the same analogy Paul uses in Romans 11, and Israel is waiting for the second coming as we look at it, while they think it is their first coming.
