The product is a service, and they agreed to a contract. Now they don't like the contract.

Is your view that contracts with the government should be meaningless? That the government should be able to unilaterally, and without recourse, change any contract they previously agreed to for any reason, and the vendor should be forced at gunpoint to comply?

If you do believe this, then what do you believe the second order effects will be when contracts with the government have no meaning? How will vendors to the government respond? Will this ultimately help or hinder the American government's efficacy?
