If God blesses those who bless Israel and curse those that Israel, then why were the conquerors of Biblical Israel greatly blessed? like Rome (1000 year empire with the blessings of birth of Christianity), while Israel’s allies were annihilated?
You're calling into question God's integrity and His decision on how the blessings are given.
Do you want an answer or do you just like to see the words you type?
Have you looked it up in scripture first?

Not a new question.
Your assumptions are incorrect though.
Jeremiah 12:1
Righteous are You, O Lord, that I would plead my case with You;
Indeed I would discuss matters of justice with You:
Why has the way of the wicked prospered?
Why are all those who deal in treachery at ease?
