Arabs plan $63 billion air power buildup

DUBAI, United Arab Emirates, Oct. 4 (UPI) -- Middle Eastern states, particularly Saudi Arabia and the United Arab Emirates, are focusing on building up their power and air-defense capabilities, a military air market expected to generate $62.9 billion over the current decade.
This concentration on procuring military aviation assets is presumably linked to current force upgrades by the six members of the Gulf Cooperation Council to counter an expansionist Iran the Arabs say is determined to acquire nuclear weapons.
