jewish why don't you answer my question?

sorry for asking but I got many answers from Christians that say we should bless the nation of Israel because God bless us and also we shouldn't curse Israel because God will curse us, I am not against that but the Jewish people of our times apply the famous verse of Abraham in Genesis, is that the reason that some countries are Ok because they have good relations with Israel? I don't know if there is something true in this idea that is come from Christians or the Bible?

You should bless Israel just because Israel deserves to be blessed and do well, not for any reward you might receive if/when you bless Israel. You should not curse Israel simply because it is in appropriate to curse Israel, not EU to any fear of punishment, dished out by God or by man.
Yes, God says He will bless those who bless Israel and curse those who curse Israel, but that shouldn't be your primary motivation unless you can't think of a better one.
Yes, in general, nations that have a good relation with Israel do between than those who don't treat Israel well, but that's attributable to the fact that those nations that treat Israel well are more moral and ethical than the ones that are trying to harm Israel, again, speaking in generalities. As an example, Gaza is an evil place which is seeking the death of Jews daily, and therefore Gazans live in self-imposed camps, not in actual cities.

Maybe you do not get answers because your question is not clear? I do not really get what your question actually is. What Verse of Abraham? What do you mean by "some countries are OK"? Does your question consider Jewish people in Israel or general?What idea (your last sentence) are you talking about? This is not clear - so if you could clear it up, people might able to answer your question.

That verse is FAR more important to (some) Christians than it is to Jews.

Judaism includes a lot of cause and effect, often reciprocal. The verse you're talking about is just another one of the 'Don't be a jerk to someone else' verses. In this case, the someone else happens to be us.

Fundamentalist Christians separate it out and read it literally, like some sort of magic formula. But then they think that there's only one covenant and only one people can be 'chosen'.

Jews just don't see it that way. Every people has their own path, Judaism is ours.

What are you doing to promote justice and fairness in this world? That's the real heart of the verse.

what is your question exactly ?
