LONDON — The United States has been supplying major combat platforms to Egypt in wake of the ouster of President Hosni Mubarak.

The Stockholm International Peace Research Institute reported that Egypt received scores of armored platforms from the United States in 2011. In a report, the institute cited the delivery of the M1A1 main battle tank to the Egyptian Army.

“In 2011 Egypt received 45 M1A1 tanks from the USA and ordered 125 more,” the report, titled “Trends in International Arms Transfers, 2011,” said.

SIPRI said the revolts in Egypt and other Middle East states did not seem to affect U.S. military exports to the region. In his last days of power, Mubarak is said to have employed the M1A1 as well as the F-16 multi-role fighter to intimidate civilian protesters.

“During 2011, the governments of Bahrain, Egypt, Libya, Tunisia and Syria used imported weapons in the suppression of peaceful demonstrations among other alleged violations of human rights and international humanitarian law,” the report, released on March 19, said. “The transfer of arms to states affected by the Arab Spring has provoked public and parliamentary debate in a number of supplier states. However, the impact on states’ arms export policies has been mixed.”

The U.S. Congress has sought to block arms exports to Egypt in wake of the arrest of Americans who work for pro-democracy non-governmental organizations. But in March the administration of President Barack Obama planned to exercise a waiver of a certification to Congress that would have halted U.S. military aid to Egypt for 2012.

“Egypt, by far the largest arms importer of the five countries, continued to receive and order major arms, in particular from the USA,” the report said. (Copyright © 2012 East West Services, Inc. 03/23/12)
