Is the current $1.5 Billion going to the Muslim Brotherhood, or the actual people of Egypt? Taking that away from the alleged corrupt Morsi regime might not be a bad thing for the new government.
Obama’s ego is too big for him to realize that the Egyptian military used the Muslim Brotherhood to get rid of Mubarak, who was setting his family up to rule For at least another generation.
A decent interval has passed and that same military no longer has any use for Morsi. If they had left Morsi alone much longer he’d have gotten rid of the next echelon of officers and the Army would have been neutered. So they had to move and move quickly.
