American Jews are not satisfied with most pro Jewish, pro Israel US President in history.
Very surprising.
No economy
In expectation of the General Resurrection of the Dead, but without full faith that Almighty God can give all a fully-functioning resurrection body
Nations have a position in the providential ordering of earthly human reality.
The righteousness or otherwise of a nation is “a thing” that matters to God…see, for example, Proverbs 14:34; although Deuteronomy 7 should put the matter beyond question.
And you need to wrestle with the implications of 2Chronicles 7:14…is this promise to Israel not also a promise to the Body of Christ in and through Him as the True Israel?
Reductionism in theology can only result in absurdity.
Likewise your concern for the authority/legality of those praying on behalf of a nation, as though God is bound by something outside Himself. Why not let God worry about these things?
Scripture (and the NT explicitly) is replete with warrant to pray on all occasions for all manner of things, and the repeated promises that God is ready, willing, and able to do even more than we can ask or imagine, Eph 3:20.
