The United States ... has much to lose if American-made tanks, rifles and helicopters are used by Egypt's military to stop rioters. A major crackdown with U.S. arms would almost certainly alienate the Eygptian public and much of the Arab world.
It's true: the US is an enabler of Egyptian military. We "invest" billions of dollars in their support. That gives our government some influence over a military which is showing itself -- at least for now -- friendly to the protesters.
The arrival of tanks and troops in Cairo's streets seemed to calm a tense situation, suggesting that the Egyptian military will play a key role as the country navigates its way out of the current crisis. On Saturday, soldiers seemed largely to sympathize with the throngs of protesters.
The massive amounts of defense aid - which have made Egypt's military one of the more effective forces in the region and yielded a relatively stable and wealthy officer class - will probably give the United States some critical leverage, Middle East analysts said.
U.S. military aid to Egypt, which totaled $1.3 billion in 2010, has held steady in recent years, even as aid for economic development, health and education has been cut. Aid to Egyptian police and riot-control forces, which amounted to about $1 million last year, is minuscule by comparison. ...WaPo
