The Torah, (first five book of the Bible, known to the Jews as The Law ) is the basis of all Western legal systems.
Hardly! More than half of the 'Ten Commandments' (assuming you mean the first ten at Exodus 20:2-17) are not recognised as laws at all in modern secular legal systems, and the first four are specifically protected against by Human Rights laws regarding freedom of worship.
The second set of Ten Commandments at Exodus 34:11-26 after Moses supposedly smashed the first set are even less relevant to modern legal systems. And only 3 bear any resemblance to any of the first set. (Slavery's fine, but you'd sure as hell better make sure you don't "boil a young goat in its mother’s milk.")
Beyond those ten (twenty?), the laws of most 'Western legal systems' protect people from things that are in 'The Law'. You can't go around raping virgins and then forcing them to marry you (Deuteronomy 22:28-29), killing foreigners and abducting their virgin daughters as sex slaves (Number 31:16-19), or forcing foreigners and their children into permanent slavery (Numbers 25:44-46), because modern laws protect against those things.
The basis of the American Constitution is based on Torah.
Rubbish. The US Constitution explicitly indicates separation from religion. And the 'one nation under God' and 'in God we trust' nonsense wasn't brought in until the 1950s.
