“why President Bush insists upon further arms for Riyadh. “
You can always count on Bush and the US state department to arm our enemies and endanger our freedom and democracy in any way they can.
The Saudis can buy their arms from any country in the world, e.g., the UK, France, Russia, China, etc. The competition is fierce. Selling arms to the Saudis helps the US in many different ways. Besides giving us leverage in how they are used, economically the sales create jobs in the US and lower unit costs to the US military. We would be fools not to sell arms to the Saudis.
