Bless or curse Israel

Just as there are Christians who are supportive of the Jewish State, there are those Christians who are not supportive of the Jewish State. Those who are supportive believe that God has a future purpose for the nation of Israel, and the promise to Abraham still applies: “³ I will bless those who bless you, And I will curse him who curses you.” Genesis 12:3 The non-supportive Christians may reject both of these things.

I've seen the non-supportive Christians to be more visible and vocal. It seems to be the spirit of the age to be anti-Israel.

One of the claims I've seen is that the promise to Abraham was to Abraham only and not to his descendants through his grandson Jacob. But even if that were true, or even if the promise doesn't specifically apply at this time, does that mean we shouldn't be supportive of the Jewish State? Should we curse Israel?

Balak, the king of Moab, sought to employ the prophet Balaam to curse Israel as they settled near them, and Moab was afraid of them. The mysterious Balaam said that he could only speak the words that God “puts in his mouth.”

⁵ Then the LORD put a word in Balaam's mouth (Numbers 23:5)...

⁷ And he took up his oracle and said: "Balak the king of Moab has brought me from Aram, From the mountains of the east. 'Come, curse Jacob for me, And come, denounce Israel!' ⁸ "How shall I curse whom God has not cursed? And how shall I denounce whom the LORD has not denounced? (Numbers 23:7-8)...

​¹ Now when Balaam saw that it pleased the LORD to bless Israel, (Numbers 24:1)...

Balaam raised his eyes, and saw Israel encamped according to their tribes; and the Spirit of God came upon him.

³ Then he took up his oracle and said: "The utterance of Balaam the son of Beor, The utterance of the man whose eyes are opened, ⁴ The utterance of him who hears the words of God, Who sees the vision of the Almighty, Who falls down, with eyes wide open: ⁵ "How lovely are your tents, O Jacob! Your dwellings, O Israel! (Numbers 24:2-5)...

"Blessed is he who blesses you, And cursed is he who curses you." (Numbers 24:9)

This last part of Balaam's prophecy speaks of a blessing and cursing, just as in the promise to Abraham. So the application goes beyond Abraham to his descendants.

But even if you say it doesn't apply at this present time, due to Israel still suffering the consequences of God's wrath for the rejection of Jesus, should we not be supportive of the Jewish State?
