Those who support the current State of Israel should note that American support of Israel has, in a practical sense, not decreased, whereas both support for the church and American power and greatness have diminished in recent decades. We bless "Israel", and yet we appear to be cursed. For those with an accurate understanding of the Scriptures, this is no surprise:

The church is the true earthly Israel, and the Church is the true spiritual Israel (i.e., the Kingdom of God).

It is utterly irrelevant how we treat the nation that calls itself "Israel", for it is a pretender to the throne. Biblical Israel was destroyed as a punishment for rejecting Christ. There is now only the Church, Militant and Triumphant. Those who bless the Church will be blessed, and those who curse the Church will be cursed.
