You stated.....”I don’t subscribe to the idea that Christians must bless them or be cursed”
God’s Word contains a clear and absolute, timeless promise relative to the Abrahamic promise of Genesis 12:3,.....The Lord had said to Abram,.... ‘Go from your country, your people and your father’s household to the land I will show you....I will make you into a great nation and I will bless you; I will make your name great, and you will be a blessing. I will bless those who bless you, and whoever curses you I will curse; and all peoples on earth will be blessed through you.”
You are assuming that the people of current day Israel are those same people. That was a promised for the past. When they are brought back, it will include ALL of the tribes, not just Jews. This is not that gathering, else they would be at peace. Every day since 1948 they have been at war.
