I disagree. 49% of Jews live in the US, and 49% live in Israel. Just like 2,000 years ago there are two kingdoms for the Jews, the Northern one (USA) and the Southern one (Israel).
Peter said that the judgment of God must begin with the house of God. The church is the house of God and I believe the tribulation must begin with God's judgement on the apostate church.
Just as Wilkerson said, if God does not judge the US He will have to apologize to Sodom and Gomorrah.
