Amazon.com founder and Washington Post owner Jeff Bezos has announced a new partnership with Boeing and Lockheed Martin, two of the largest weapons contractors in the world. Bezos’s private space company Blue Origin will partner with United Launch Alliance, a joint venture of the two weapons makers, to create rocket engines to launch military satellites. Bezos bought The Washington Post and a number of other publications last year for $250 million, less than 1 percent of his wealth which at the time was estimated at $28 billion.
