You have a fundamental misunderstanding of ZC's position about the relationship between Jews and the rest of the world.
It is perhaps clarified by these passages from Isaiah chapter 60:
10 "Foreigners will rebuild your walls,And Chapter 61:
and their kings will serve you.
Though in anger I struck you,
in favor I will show you compassion.11 Your gates will always stand open,
they will never be shut, day or night,
so that men may bring you the wealth of the nations
their kings led in triumphal procession.12 For the nation or kingdom that will not serve you will perish;
it will be utterly ruined.13 "The glory of Lebanon will come to you,
the pine, the fir and the cypress together,
to adorn the place of my sanctuary;
and I will glorify the place of my feet.14 The sons of your oppressors will come bowing before you;
all who despise you will bow down at your feet
and will call you the City of the LORD,
Zion of the Holy One of Israel.15 "Although you have been forsaken and hated,
with no one traveling through,
I will make you the everlasting pride
and the joy of all generations.16 You will drink the milk of nations
and be nursed at royal breasts.
Then you will know that I, the LORD, am your Savior,
your Redeemer, the Mighty One of Jacob.17 Instead of bronze I will bring you gold,
and silver in place of iron.
Instead of wood I will bring you bronze,
and iron in place of stones.
I will make peace your governor
and righteousness your ruler.18 No longer will violence be heard in your land,
nor ruin or destruction within your borders,
but you will call your walls Salvation
and your gates Praise.19 The sun will no more be your light by day,
nor will the brightness of the moon shine on you,
for the LORD will be your everlasting light,
and your God will be your glory.20 Your sun will never set again,
and your moon will wane no more;
the LORD will be your everlasting light,
and your days of sorrow will end.21 Then will all your people be righteous
and they will possess the land forever.
They are the shoot I have planted,
the work of my hands,
for the display of my splendor.22 The least of you will become a thousand,
the smallest a mighty nation.
I am the LORD;
in its time I will do this swiftly."
5 Aliens will shepherd your flocks;
foreigners will work your fields and vineyards.6 And you will be called priests of the LORD,
you will be named ministers of our God.
You will feed on the wealth of nations,
and in their riches you will boast.7 Instead of their shame
my people will receive a double portion,
and instead of disgrace
they will rejoice in their inheritance;
and so they will inherit a double portion in their land,
and everlasting joy will be theirs.8 "For I, the LORD, love justice;
I hate robbery and iniquity.
In my faithfulness I will reward them
and make an everlasting covenant with them.9 Their descendants will be known among the nations
and their offspring among the peoples.
All who see them will acknowledge
that they are a people the LORD has blessed."10 I delight greatly in the LORD;
my soul rejoices in my God.
For he has clothed me with garments of salvation
and arrayed me in a robe of righteousness,
as a bridegroom adorns his head like a priest,
and as a bride adorns herself with her jewels.11 For as the soil makes the sprout come up
and a garden causes seeds to grow,
so the Sovereign LORD will make righteousness and praise
spring up before all nations.
