Another 80 people died in violence in Egypt on Friday, as Muslim Brotherhood crowds protested the military crackdown on their sit-ins that cost hundreds of lives this week. Some of the violence resulted fro police heavy-handedness, some from an armed Brotherhood attack on a police station. The continued unrest upped the pressure on the Obama administration to cut off military aid to Egypt. It is the only legal and ethical thing to do, but here are some reasons it has been difficult for Washington to take that step.

1. The US doesn’t give much aid to the Egyptian people per se. Only $250 mn a year out of $1.55 bn is civilian. The aid is to cement a relationship between the Egyptian officer corps and the Pentagon.

2. The military aid, $1.3 billion a year, is mostly in-kind, a grant of weaponry . It must be spent on US weapons manufacturers. It is US arms manufacturers like Lockheed-Martin and General Dynamics (and their employees) who would suffer if it were cut off.

3. The Congress gave the Egyptian Generals a credit card to buy weapons, and they’ve run up $3 billion on it for F-16s and M1A1 tanks. If the US cancelled aid, the US government would still have to pick up that bill.

4. Even most of the civilian aid is required to be spent on US goods and materiel. It is corporate welfare for the US

5. The aid was given as a bribe to the Egyptian elite to make nice with Israel. Given the chaos in Sinai, and Egypt’s instability, Congress is more worried about that issue than at any time in 40 years.

6. The Israelis asked the US not to suspend the aid.

7. Congress even structured the economic aid to require some of it help joint Israeli-Egyptian enterprises in Egypt, so some of the aid to Egypt actually goes to . . . Israel.

8. It is not generally recognized, but the Egyptian military provides a security umbrella to Saudi Arabia, Kuwait and the UAE against Iran (and sometimes Iraq). The Gulf oil states also have powerful Washington lobbies and want Egypt to continue as a Gurkha force. Children, can you say oil?

9. Many in Congress don’t actually disagree with the generals’ actions in overthrowing the Muslim Brotherhood-backed Freedom and Justice Party and driving it underground, since they agree it is a terrorist organization

10. Behind the scenes Egyptian military intelligence has helped the US track down Muslim extremists and in the Mubarak era ran black sites where they tortured suspected al-Qaeda for Washington. The US deep state would like to ramp that relationship back up.
