The real power behind The Versailles Treaty, those who drafted it, were those who held the power at the end of WW1:-

David Lloyd George - a Welsh Baptist

Georges Clemenceau - a French anti-clericalist

Woodrow Wilson - an American Presbyterian

Vittorio Emanuele Orlando - an Italian catholic

So even if there was a majority of Jews at the actual signing (which I very much doubt), who cares?
