There is always nepotism at play when there are 2 jews in a business deal, and any number of non jews.
The jews do not even need to know each other, or agree beforehand.. they know that when it comes down to it, they will have each others backs.
Even if the two jews are on separate sides of the aisle in politics, religion, or any other superficial distinction.
This is how 12 million have conquered 900 million. We have been individualistic, and "fair".. while they are collectivist, and unfair.
They have two sets of Moral codes, those that apply to in tribe matters, and those that apply out of the Tribe.
